http in node - related question. #4482

Closed VINISHVV closed 1 month ago

VINISHVV commented 1 month ago

Current Behavior

Dear All,

I am a big fan of node-red projects from last one year. Recently i installed a flowfuse self hosted version for upgrade existing node-red flows.

I have created a new instance in flowfuse which is accessible from both editor menu and directly accessible through the domain name shown in flowfuse.

I have added an http in node in the new instance flow which support post methods. But i m unable to send any data to this node as its showing error.

can you help with this issue.

Expected Behavior

The flow needs to starts basis the input received in the http in node.

Steps To Reproduce

Create a new instance. and deploy required flows. Map the domain A record for access the new instance add an http in node in the newly created instance. initiate a post method APi call to the end point created.

Environment

Have you provided an initial effort estimate for this issue?

Hello,

Can you share some more details about this please, specifically the errors that are shown, and also fill out the environment section of the template so we know what version of FlowFuse and how you installed it.

Also how big is the data you are posting to the http-in node path?

VINISHVV commented 1 month ago

@hardillb - modified the details

hardillb commented 1 month ago

@VINISHVV You've not shown the error or said how you are running FlowFuse (Docker or Kubernetes).

Without knowing the error we can't know what the problem might be

VINISHVV commented 1 month ago

@hardillb i am running my flowfuse in AWS ( https://aws.amazon.com/marketplace/search?prevFilters=%257B%2522ref_%2522%3A%2522mp_nav_category_96c2cd16-fe69-4b18-99cc-e016c61e820c%2522%2C%2522category%2522%3A%252296c2cd16-fe69-4b18-99cc-e016c61e820c%2522%257D&searchTerms=flowfuse )

Error i am gtting in postman

OK, that is returning the flowfuse home page. Which implies that the request is being sent to the hostname for the FlowFuse application, not the Node-RED instance.

To help we really are going to need to know the hostnames you are using here and how you've setup the DNS.

Assuming the following:

Then you should be pointing postman at https://instance1.example.com/path where /path is the value entered into the http-in node config dialog.

If that is what you are using, then I will need to see the logs from the nginx container in the AWS machine.

hardillb commented 1 month ago

But the fact you said you can access the Node-RED editor on it's dedicated hostname that implies that nginx should be working correctly

To help we really are going to need to know the hostnames you are using here and how you've setup the DNS.

Assuming the following:

  • The FlowFuse application is running on forge.example.com
  • The instance is running on instance1.example.com

Then you should be pointing postman at https://instance1.example.com/path where /path is the value entered into the http-in node config dialog.

Your understanding is absolutely correct!

i can access the editor using the domain name ( example https://instance1.example.com )

hardillb commented 1 month ago

Then as I said I'll need access to the following:

You can get both of these by using SSH to connect to the AWS EC2 machine, the same as when you ran through the setup wizard when you installed from the marketplace.

Ahhh,

How have you configured security for the HTTP end points for that instance in the FlowFuse Application?

image

Have you enabled FlowFuse User Authentication?

If so you will need to included a user security token in the header (Authorization: Bearer [token]) when making the request.

You can generate a user token under the security settings for your user

VINISHVV commented 1 month ago

@hardillb - Thank you. The issue is related to my limited knowledge; I have not added the token in my API request.
