Django python service not starting

After creating a python 3.10.1 build the startCommand is not running

This is the last message I get to see and the logs tab is empty

Generating container image from build...

The start command is set to

gunicorn app.wsgi -b

And the django allowed hosts is set to *

Hi there,

Can you make sure that the RENDER_EXTERNAL_HOSTNAME is added to the allowed hosts list explicitly based on these docs for deploying Django?
