I cannot resolve this issue; the service is unable to update and run new modifications after updating the files.

Bro this error means your container can’t find main.py at /app/main.py. It’s not a Python issue, it’s a path/deployment problem.
Do this step by step:
- First check if the file even exists inside container: docker exec -it <container_id> sh ls /app → If main.py is not there, that’s the issue
- Check your project structure Make sure main.py is actually inside your project root (or wherever you're copying from)
- Fix Dockerfile (very important) It should look like: WORKDIR /app COPY . . CMD ["python", "main.py"]
- Rebuild properly (your issue is probably old container running): docker-compose down docker-compose build --no-cache docker-compose up -d
- If using volumes:
volumes:
- .:/app → then your local folder MUST have main.py
Most likely your container is using old build or wrong path. Rebuild clean and it’ll work.
If still not working, send me your Dockerfile + folder structure.

Bro this error means your container can’t find `main.py` at `/app/main.py`. It’s not a Python issue, it’s a path/deployment problem. Do this step by step: 1. First check if the file even exists inside container: docker exec -it <container\_id> sh ls /app → If main.py is not there, that’s the issue 2. Check your project structure Make sure main.py is actually inside your project root (or wherever you're copying from) 3. Fix Dockerfile (very important) It should look like: WORKDIR /app COPY . . CMD \["python", "main.py"\] 4. Rebuild properly (your issue is probably old container running): docker-compose down docker-compose build --no-cache docker-compose up -d 5. If using volumes: volumes: * .:/app → then your local folder MUST have main.py Most likely your container is using old build or wrong path. Rebuild clean and it’ll work.

I deleted most of the files and rewrote them, but the problem persists. Realway.com can't find the main.py file.

still not railway's fault. you said you "deleted most of the files" that doesn't help us at all. Show a screenshot of your project folders. the error clearly says there is no such file in /app/main.py so check your /app folder to see if main.py is in there.
Hint: It's not.
