I ran Python, FastAPI, and PostgreSQL as docker-compose, but it doesn’t work with these errors.
I don’t know why this error occurs.
Full Error Message:

No problem, glad to hear!
You might want to consider putting all your python code into a ‘src’ folder, it’s a good practice to have only the files you need inside the docker container and that makes it so you can just build it with the entire folder.
Outside of the src folder you’d keep your docker files, dependencies and such.
