I am using Python and fasatpi (web framework). My application.py file is:

from fastapi import FastAPI
import uvicorn

application = FastAPI()


@application.get("/")
def read_root():
    return {"Hello": "World"}



if __name__ == "__main__":
    uvicorn.run("application:application", host="127.0.0.1", port=5000, log_level="info")

This runs fine on local machine by running python application.py

However when I deploy to an elastic beanstalk on AWS, after multiple failed attempts and also experimenting with a Procfile, as follows:

web: uvicorn application:app --host=0.0.0.0 --port=${PORT:-5000}

And repeated error is:

How can I fix this? Many thanks.
