Deploying Python FastAPI to AWS Beanstalk

Question

I have a small python FastAPI project which is completely working on my local computer. But when I try to deploy it to AWS Beanstalk (manually for now) I’ve always got a ‘502 Bad Gateway’ error when open the application in a browser.
This is my project structure:

/project
   /html/
   main.py
   Procfile
   requirements.txt

the main.py contains the api endpoints that use some HTML files. These files are in the html/ folder.
The Procfile looks like this:

web: uvicorn main:app --host 0.0.0.0 --port 80

and the requirements.txt like this:

fastapi~=0.91.0
uvicorn

When I uploaded an example application from AWS to the same Beanstalk environment, it worked. And as I said, even if I execute the python project locally, it works fine. So I must have configured something wrong.

Does anybody know this problem and know how to fix it?
