If your function is working locally - and deploys successfully but no files or functions are visible after deployment - this is potentially the issue: https://github.com/Azure/azure-functions-python-worker/issues/1262#issuecomment-1784778748

[saikumaru]

Thank you @jsm-NK for your reply.

1. Unfortunately we dont have a way to find out which library is causing that issue, if at all, in our case.
2. If we provide a version number in requirements.txt, it is not supposed to download an "unexpected version from PyPI".
3. The libraries in my requirements file dont seem to be part of a python base installation.

Quick follow up - After deploying, do you see any files if you go on "app files" instead of going to overview/code/test ?

Have you configured all your application/configuration settings in azure?

[bhagyshricompany]

Thanks for reporting will check and update.

All I had in my requirements.txt file was azure-functions and I still saw this.

Adding a comment to this ticket as well since this one is open. (#1262 is closed)

All I had in my requirements.txt file was azure-functions and I still saw this.

Saw what, exactly? The issue in #1262 can have many causes. Do you built locally and do a ZIP deployment? Do you perform a remote build? I have a special repo with reproducible steps for the issue of 'Functions not showing in Azure Portal', and they all have the same issue: there is an unhandled exception raised in the root of your script or imports. The reason may vary:

• You do a ZIP deployment, but perform the pip install step on a Windows machine, while deploying to a Linux machine and one of your dependencies was specifically downloaded for Windows;
• You have a relative import that doesn't work;
• You get an environment variable that doesn't exists in the root of your .py file with my_var = os.environ('MYVAR') (this will raise a KeyError if MYVAR doesn't exists);

Etc. There are countless ways to induce this behavior and the only thing Microsoft has to do is to propagate the exception raised to Application Insight so we can actually see what is wrong.

If you have no idea what is wrong: pull everything in the scope of your function method. So, rather than doing this:

import azure.functions as func
import my_package
import os

myvar = os.environ("MYVAR")

app = func.FunctionApp()

@app.function_name(name="HttpExample")
@app.route(route="hello")
def test_function(req: func.HttpRequest) -> func.HttpResponse:
    return func.HttpResponse("HttpExample function processed a request!")

Try this:

import azure.functions as func

app = func.FunctionApp()

@app.function_name(name="HttpExample")
@app.route(route="hello")
def test_function(req: func.HttpRequest) -> func.HttpResponse:
    import my_package
    import os

    myvar = os.environ("MYVAR")
    return func.HttpResponse("HttpExample function processed a request!")

Now call your function and see what exception you get. If you don't get an exception, then at least you can move back the lines of code one by one to pinpoint which one is causing issues.

[charlesjankowski]

Thanks for you great feedback and insights on this problem!

My use case is pretty simple; I create an HttpTrigger, then I create another one in a new blueprint file, and do the import and register_functions in function_app.py. As such:

• I have no entries in requirements.txt except for azure-functions.
• The only relative import I have is importing the blueprint so I can register it. When I comment out the register_app but not the import, it works fine, i.e., I see the function on the portal. So presumably the import is fine.
• I'm not accessing any environment variables.

Right now, I'm thinking the only way out is to back off to V1, which seems to work fine.

Yes, I look forward to some logging that will pinpoint the source of the problem.

Thanks again!

@charlesjankowski you say register_app but did you mean register_functions? If so, please try register_blueprint on the imported blueprint. Otherwise, without code example, it's hard to point to a problem to be honest. Good luck!

[pdthummar]

@charlesjankowski: Could you please share the code and steps for replication, if available? Additionally, I'd like to know if you intend to deploy it to a Consumption or an EP app. Thanks

@saikumaru :- I'd like to know if you intend to deploy it to a Consumption or an EP app. Thanks

[charlesjankowski]

@JarroVGIT thanks for correcting my error, yes I meant register_functions() (since that's what was in the instructions in the newly created blueprint file). I replaced with register_blueprint() and get the same.

Here's my code https://github.com/Grapevine-Health/cj20231029a

Right now it's Consumption, which was the only one available for Python 3.10 US-East (unless I'm wrong on that).

[pdthummar]

@charlesjankowski I see what's potentially happening in your case. The issue arises because you have a variable named blueprint and a function with the same name in your blueprint.py. When you import blueprint using from blueprint import blueprint in your function_app.py file, Python gets confused because it tries to import both the variable and the function with the same name, leading to a naming conflict. To resolve this issue, you should consider renaming either the variable or the function to avoid the naming conflict.

In addition to, All available SKUs support both Python 3.10 and Python 3.11. Thanks

[charlesjankowski]

@pdthummar Thank you, that seems to work now!

I used the VSCode-created blueprint.py unmodified; perhaps it would be good for the auto-generated example to not cause such errors. It did ask for both the blueprint filename and the new function name, so that's arguably on me, but perhaps the sample could call the azure.functions.Blueprint object (and the decorator) FILE_bp or something like that just to minimize the chance of conflict.

In any case, indicating some kind of error during the deployment process would be great.

Also, both app.register_functions() and app.register_blueprint() seem to work; is there a different/preference?

Thanks again!

@saikumaru :- I'd like to know if you intend to deploy it to a Consumption or an EP app. Thanks

Thank you for your reply. We need to deploy it to a Linux consumption plan. Rest of the steps followed to deploy it are as per the MS document quoted.

Have you configured all your application/configuration settings in azure?

Yes, I can see the latest files under "app files"

The settings have been updated as per the documentation of MS, so yes they are all configured correctly.

[pdthummar]

@saikumaru I successfully deployed the function to the Azure Functions Consumption Plan using the provided source code. I used the following command to publish it: func azure functionapp publish . Could you please attempt to redeploy it and share additional details if you encounter any deployment issues?

[saikumaru]

Thank you! I will try that. But does the function show up on the portal though please?

I had successful deploys earlier too, but they didn't show up on portal.

[pdthummar]

@saikumaru Yes, Function is showing up in portal and works as expected.

[saikumaru]

@pdthummar no luck, sorry. Can you please retry deploying, with a few edits to the debug messages, just to be sure.

More importantly, is there a way for us to see what is going wrong once this is deployed please? Perhaps some app logs etc.

@mk7exe - Checking the issue and why was this issue not surfaced. I see the exception in the backend, and it looks like an issue on our end. I'll get that fixed asap and release it in the latest version of the azure-python-functions-durable.

The issue with logs not showing up - I am investigating that on my end and checking how to surface this. Most likely the logs would be on AppInsights and not on the build system.

[saikumaru]

Thank you @vrdmr ! That would be really helpful to have that logs, please keep us updated. if you have access to look at the backend logs, here is the app

[saikumaru]

@saikumaru Yes, Function is showing up in portal and works as expected.

@pdthummar Hope you had a chance to check my reply. However Id like to reconfirm if you have used both my files as-is when you tested and deployed it(Py version=3.9.13)?

[mk7exe]

Thanks @vrdmr. I'm looking forward for your updates

[pdthummar]

@saikumaru I tested with python3.10 earlier and worked without any issues. but i have tried to test it with python3.9 and experienced same issue. It appears to be a qdrant-client 1.2.0 conflicting libraries issue. In your remote build log, I've observed a below warning message that is potentially causing the issue. qdrant-client 1.2.0 requires pydantic<2.0,>=1.8, but you'll have pydantic 2.4.2 which is incompatible. qdrant-client 1.2.0 requires typing-extensions<4.6.0,>=4.0.0, but you'll have typing-extensions 4.8.0 which is incompatible.

As a result of this compatibility issue, the worker is failing to index functions with below error, due to this, functions aren't visible in the portal.

Error

To address the issue, I attempted to utilize qdrant_client without specifying a specific version in requirements.txt (i.e., not using qdrant_client==1.2.0). After redeploying, I observed that the function is now accessible through the portal. (Using Python3.9)

I would suggest retrying deployment with above mitigation. Thanks

[saikumaru]

@pdthummar thank you very much for persistently looking into this. I will give it a try and hopefully this should be it. Can you confirm if this error was on your local or remote please, and if it's remote where exactly can these be viewed?

But I wish I could have seen these logs on remote as well, or the portal say at least something about why the function dint show up. In v1 we were able to view logs but v2 doesn't show these reasons.

[saikumaru]

@pdthummar that has worked, thank you!

As a result of this compatibility issue, the worker is failing to index functions with below error, due to this, functions aren't visible in the portal.

Please can you advise how and where we can look up that failures?

[saikumaru]

The issue with logs not showing up - I am investigating that on my end and checking how to surface this. Most likely the logs would be on AppInsights and not on the build system.

@vrdmr would you have an update on this please, so that we can debug similar errors.

[jmandivarapu]

I am having similar issues where ....

1. I deployed the python functions using VS code (It works and all the functions show up including all the files)
2. Deploying using the Azure Devops - App files got updated but NO FUNCTIONS

Tried all possible plans but none of seams to work. I am currently using Python 3.10 and V2 function. All logs in deployment center doesn't show any error.

My requirement function is : azure-functions

[pdthummar]

@saikumaru We are actively addressing this matter to offer users more clarification on such issues. We will provide an update once we make progress on this. I am closing this issue for now. Thanks

@jmandivarapu If you are still facing the issue, please open new issue. Thanks

[tomasfernandez1212]

Plus one.

It is very frustrating to debug issues that occur outside of the function definition.

For example, import errors, missing dependencies, or issues with the binding and trigger definitions.

We are essentially flying blind when trying to debug these problems.

Azure Functions should provide more access to logging that can lend a light to these issues.

[erfannariman]

@saikumaru We are actively addressing this matter to offer users more clarification on such issues. We will provide an update once we make progress on this. I am closing this issue for now. Thanks

@jmandivarapu If you are still facing the issue, please open new issue. Thanks

Why was this issue closed while this clearly is an ongoing issue? Is there an other topic where we can follow the progress on this issue?

[BDParwez]

In case that it is not visible means that there is either missing an dependency (why pip freeze resolves the issue) or an dependency cannot be installed on the serverless instance. I had an issue with the psycopg2 package.

[mk7exe]

@BDParwez I’m pretty sure that is not the case. I deployed the same function with the same dependencies in V1 and everything works fine. Same function in V2 has the issue of functions not being visible in the portal and not being callable.

[stock-ds]

I had the same issue and found the actual error by opening MyAzureFunction/Monitoring/Log Stream/Filesystem Logs and deploying the function.

I saw an error that imports were broken even though VS code said deployment was "successful" and function did not appear. Fixed this error and now function appears.

EDIT:

Added more code and it no longer shows any other errors in that log stream and function does not appear...

I found the actual actual error by setting up WSL in VS code and running the function there. It immediately threw the error which azure eats up. It was a keras model which works in windows but doesn't work in linux, I just re-saved this model using WSL, tested locally, and now functions appear in Azure.

Azure should just throw these errors instead of silencing them and saying that the deployment is successful...

TLDR: Use WSL to test your function locally

[harsh098]

Experiencing a similar issue here too...

[JanKrl]

The same issue using Python V2. Deploying from vscode worked. Deploying a zip did not work even though the code was visible in Azure Portal. Switching to Python V1 solved the problem.

[TheBestMomo]

Microsoft recently updated their documentation, and the solution is to add the following code to the pipeline YAML file:

• bash: | if [ -f extensions.csproj ] then dotnet build extensions.csproj --output ./bin fi pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt

Here are the Microsoft documentations that describe the error and solution https://learn.microsoft.com/en-us/azure/azure-functions/recover-python-functions?tabs=vscode%2Cbash&pivots=python-mode-decorators#functions-not-found-after-deployment

Hi all,

I was running into the same issues mentioned above. I was using the Deployment Center in the Azure Function App to connect it to my GitHub, and no matter which packages I installed inside my requirements.txt file—even something as common as requests—the function trigger would not show up in the portal when deployed because it couldn't find the packages.

The solution I found was to zip up the library packages during the GitHub build instead of letting Oryx do the remote build. Here are the changes I made to the GitHub workflow file to achieve this:

1. Inside the "Install dependencies" step of the build job, change the pip install command pip install --target=".python_packages/lib/site-packages" -r requirements.txt
2. Inside the "Zip artifact for deployment" step of the build job, change the zip command so it includes the python_packages zip release.zip .python_packages ./* -r
3. Inside the "Deploy to Azure Functions" step of the deploy job, change these values so it doesn't do a remote build scm-do-build-during-deployment: false enable-oryx-build: false

This way you can still use the V2 programming model and can use Github Actions instead of VSCode to deploy to the Azure Function.

Thanks so much pk556 (and others). I was running into this as well and pulling my hair out. My python func deployed fine when using basic auth/github cicd, but this issue manifested when I tried to instead use User Managed Identity/Federated and sync CICD to github.

The steps pk556 outlined finally and immediately resolved the missing functions issue for me.
