backend and frontend not communicating

[sud-quantum]

================== First issue building docker ==================

--> I clone the repo in a VM
--> created the .env file in both the frontend and backend
--> used " docker compose up --build " to build the app
--> successfully built
--> the UI aka frontend loaded successfully
--> trying to connect to the DB using URI and password
--> $$$$$$$ Network error is coming i think the backend and frontend are not communicating

---

================== Second issue running only the backend ==================

--> I clone the repo in a VM
--> create a .env file in the backend
--> create a venv in the backend
--> installed the requirements file
--> started the app using " uvicorn score:app --reload "
--> using postman i used /upload, /extract
-->while /upload it's uploading and i can able to see it in the neo4j labs
??????? whether it will store it in the any of the dir?
--> in the /extract i am getting

{
    "status": "Failed",
    "error": "Error while reading the file content or metadata, libGL.so.1: cannot open shared object file: No such file or directory",
    "message": "Failed To Process File: file_name or LLM Unable To Parse Content Error while reading the file content or metadata, libGL.so.1: cannot open shared object file: No suc",
    "file_name": "file_name"
}

i tried in the local in there
while /upload

{
    "status": "Success",
    "data": {
        "file_size": 35635,
        "file_name": "insur_with_comments_sample_data",
        "file_extension": "file_name",
        "message": "Chunk 1/1 saved"
    },
    "message": "Source Node Created Successfully"
}

while /extract

@sud-quantum have you resolved this issue..?

I encountered a similar problem. The uvicorn backend is by default only listening on localhost:8000 however the frontend web app is attempting to connect in web browser client context to the VITE_BACKEND_API_URL defined in the frontend/.env which is by default http://localhost:8000

This can only ever succeed if your backend (uvicorn) server and frontend (VITE) server and web browser are all running on the same host. For example, if you were developing on a laptop and running everything locally.

If that's not the case, you need to make sure the backend (uvicorn) listens to all interfaces. You do that by adding --host 0.0.0.0 to the command line, e.g.
uvicorn score:app --host 0.0.0.0 --reload

Then you need to change the value of VITE_BACKEND_API_URL defined in the frontend/.env to something which makes sense for both your frontend server process and your web browser, e.g.
VITE_BACKEND_API_URL="http://your-backend-hostname:8000"

After making these changes, frontend and backend were able to communicate in my experience.
