Django Gives "502 Bad Gateway" Error On Google App Engine

I'm trying to deploy a Django application on Google App Engine in the Standard Python3.8 environment. I followed all the steps in this document. App runs fine on my local with goog

Solution 1:

The application is complaining about not finding the main module, the document that you mentioned aboards a different problem than yours, you're not reaching the point of using the storage library.

Regarding your specific problem. As mentioned in the documentation:

The runtime starts your app by running the command you specify in the entrypoint field in your app.yaml file.

In this case your app.yaml isn't specifying an entrypoint, when this happens you have to make sure that you fulfill the next requirements:

If your app meets the following requirements, App Engine will start your app with the gunicorn web server if you don't specify the entrypoint field:

The root of your app directory contains a main.py file with a WSGI-compatible object called app.

Your app does not contain Pipfile or Pipfile.lock files.

In this case your application is lacking the main.py file which is the error App Engine is complaining about. There are multiple ways to avoid this error (like specifying an entrypoint). What I suggest in this case is to create a file named main.py on your root folder of your app and include the next:

from mysite.wsgi importapplicationapp= application
