This 500 error you are receiving could be due to missing libraries (flask) since I do not see a requirements.txt on your github. Please follow our quickstart <https://cloud.google.com/appengine/docs/standard/python3/quickstart> on how to get started with Python 3.7 which covers how to install libraries using a requirements.txt. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
