I already made the change and it didn't work, But he appeared to me now to select the limits.

Share your repo please, you have something configured incorrectly at the project level.

This is my repository, anyway my project was already working, but it stopped working overnight, without having sent any commit

This is a fast API app, thus you need to run the app with uvicorn.

Obviously it works with uvicorn, and it is installed with requirements.txt, but it still doesn't work, in fact I just updated the dependencies and everything, in fact I have other apps deployed with fastapi and they are working
