You have env: flex which means you are trying to use GAE Flexible. There are a few things in your code incompatible with Flexible:

  1. You cannot specify instance_class: B8. Instance classes are from GAE Standard. Instead, leave it out entirely or specify resources

  2. You cannot specify basic_scaling. This is also from Standard. Instead specify automatic_scaling or manual_scaling.

  3. You are running gunicorn with main:setup, but you are using object app in module setup, so you should use setup:app.
