I am making a Flask API that I try to containerize.

I am using the google_auth_oauthlib module to get the authorization from the user of my application to use his YouTube account.

This is performed in the _get_authenticated_first_time function of this python file.
It works fine on my local server.

However, when I am tying to containerize my application with Docker, the function flow.run_local_server runs forever without redirecting me anywhere.

I tried to pass as port argument of the flow.run_local_server() the value 8080 and map my local port 8080 to the port 8080 of the container in my docker-compose.yaml file but it doesn't work either.

So my question is simple:
Do you know how to make a set up that allows to run the authentication flow inside a Docker container?
