Unable To Start Webapp

[spenpal]

Describe the bug I get the Error: connect ECONNREFUSED 127.0.0.1:8000 error when I try to run npm run dev, so I tried to run npm run fastapi-dev in another terminal. However, I get an error saying: sh: 1: source: not found.

Full bug error from npm run fastapi-dev:

> webapp@0.1.0 fastapi-dev
> source ../env/bin/activate && pip install -r ../requirements.txt && python -m uvicorn backend.api.index:app --reload

sh: 1: source: not found

To Reproduce Steps to reproduce the behavior:

1. Type npm run fastapi-dev.

Desktop:

• OS: WSL2 (Ubuntu 22.04.3 LTS)

Thanks @spenpal for raising the issue.

@Sayvai can you take a look into this ?

[Sayvai]

@spenpal - when you ran npm run fastapi-dev, was your current working directory within the webapp/ sub-directory?

[spenpal]

@Sayvai Yes, I was in the /webapp directory when I ran the command

[Sayvai]

@spenpal I believe that since you're running a Windows WSL ubuntu shell, the error message you're seeing; sh: 1: source: not found, indicates to me that your WSL shell does not recognise the source command. I developed the script under a Mac OS environment, and hence the assumption that source would work across all systems.

So try this.

In webapp/package.json file, and for the fastapi-dev script, temporarily replace source with a period (.) instead.

- "fastapi-dev": "source ../env/bin/activate && pip install -r ../requirements.txt && python -m uvicorn backend.api.index:app --reload",
+ "fastapi-dev": ". ../env/bin/activate && pip install -r ../requirements.txt && python -m uvicorn backend.api.index:app --reload",

Save the change locally, and try running npm run fastapi-dev again.

If that works, then I'll raise a PR for that fix, so that the npm script will work in both Mac OS and Windows WSL Ubuntu shell environments.

This is my new error, after making the changes you suggested.

> webapp@0.1.0 fastapi-dev
> . ../env/bin/activate && pip install -r ../requirements.txt && python -m uvicorn backend.api.index:app --reload

sh: 1: .: cannot open ../env/bin/activate: No such file

[Sayvai]

@spenpal the following error message suggests that the Python environment activation script (../env/bin/activate) is not found, and so implies you may not have setup the Python Virtual Environment correctly?

sh: 1: .: cannot open ../env/bin/activate: No such file

Given that, did you visually inspect that the env/bin/ directory exist from the root of the project? And whether the activatescript exist within that directory?

If the directory and script does not exist, then that suggests the Python virtual environment (named env) was not setup (or just not setup correctly). If so, then I suggest that the Python setup instructions is followed, which is set out in the projects' root README.md file (step 3 and 4), that is also referred to from the webapp/README.md instructions.

[srbhr]

@spenpal is this issue fixed now?

[spenpal]

@srbhr I realized my initial issue. I use a package manager called PDM, which uses virtualenv by default, for virtual environments. But, the virtualenv environment folder's default name is .venv, instead of env, as stated in the setup instructions.

I changed the script command to reflect my setup, and it works perfectly fine now. "fastapi-dev": ". ../.venv/bin/activate && python -m uvicorn backend.api.index:app --reload",

This is what I get now at the frontpage of the webapp:

I am getting the following debug messages. Not sure if it is pertinent to successfully run the app because I am getting the default screen for the Common Words between Job Descriptions and Resumes Highlighted and Suggestions, even after uploading my resume and job description.

[1] DEBUG Error retreiving service keys:

[Sayvai]

@spenpal

1. the following error from the FastAPI server is nothing to be concerned about, and is just a background web app initialisation check which informs us that no service keys were found:

[1] DEBUG Error retreiving service keys:
[1] INFO:     ::ffff:127.0.0.1:0 - "GET /api/service-keys HTTP/1.1" 500 Internal Server Error
[0] No configurable service keys found. If this is unexpected, please check the GET API response to '/api/service-keys'.

Until recently, the scripts/similarity/config.yml was removed by the maintainer, due to the fact that a third-party service (cohere? qdrant?) no longer provides free API keys for the overall project to work.

2. I would advise that your localisaed frontend web app changed to the npm package.json script changes are not committed to remote, as the official project environment name to be used is env (not .venv).

---

3. Also worth noting that the full stack web app currently returns fake results for demonstration purposes of its capabilities, and so is still under development. So I would not rely on the web app for real results. And if you're intending to get real results, and do not plan on contributing to the development on the web app, then i suggest you run the Streamlit app instead, provided you have signed up for the necessary API keys.

Hey @Sayvai , I'm on Windows and not using WSL. Just have NodeJS and Python.

The Python virtual environment is activated via env/Scripts/activate instead of env/bin/activate. Would it be okay to add another script in package.json for Windows-targeted folks?

Probably need to add this:

"fastapi-dev-win": "..\\env\\Scripts\\activate && pip install -r ../requirements.txt && python -m uvicorn backend.api.index:app --reload",
"dev-win": "concurrently \"npm run next-dev\" \"npm run fastapi-dev-win\"",

Followed by: npm run dev-win

Note: I have done this in my local workspace and not planning to push to main yet.

[Sayvai]

Hey @imhalcyon,

Thanks for highlighting this particular issue for Windows (non-WSL) users. That makes perfect sense, and I agree with the consistent naming conventions for the additional npm scripts / tasks suggestions.

If you don't mind, please create a fork of the main repository with the suggested changes, and then open a detailed PR which links back to this issue, in which the PR itself is configured to merge into main as the base branch.

Good spot!

Done. Please check whenever possible: https://github.com/srbhr/Resume-Matcher/pull/185

[SnehaJainM]

Hey, could you please tell me where can i find: (https://github.com/srbhr/Resume-Matcher/blob/main/webapp/README.md ) the webapp readme file?

[srbhr]

Hi @SnehaJainM The web-app is in the web-app branch and inside the web-app folder is the readme
