I am running into this error while deploying my django(2.1) app with python(3.5) to appengine. Before, I was using python 2 and python27 in app.yaml, there was no such error, but now when I have python 3.5.2 and python37 in my app.yaml, I am running into this error after "gcloud app deploy". Do I really have to enable billing or am I doing something wrong? Is there a way out? The full error is
