I would like to use Google Cloud Endpoints with GAE using the newly (summer 2018) released Python 3.7 standard environment. However, no matter what I try, I cannot seem to get http requests to go through the Endpoints service. They seem to get routed straight to the GAE code, without e.g. any authentication (API key checking) being performed. When I use GAE flex environment it works fine however.
Any suggestions what to try/check? When I look on Google Cloud Console under Google Endpoints, I see the deployments of the service for the correct app domain (with version 0.0.1). I also see the methods listed as per my openapi YAML file. However, I do not see any requests show up in the tracking chart.
