API management for multiple APIs only work for one.

[zjaml]

I struggled to get multiple APIs working correctly for days.
After I deployed the service using the steps below, although both api require api key, the problems are:

1. I can call one of them without providing api key while the other does require an api key.
2. Only one of the API are showing up in developer portal. Sometimes AuthedGreetingApi, sometimes GreetingApi.

Is this a bug for cloud endpoints?

python lib/endpoints/endpointscfg.py get_openapi_spec main.GreetingApi main.AuthedGreetingApi --hostname inner-cinema-211407.appspot.com --x-google-api-name

this generates greetingv1openapi.json and authedgreetingv1openapi.json

gcloud endpoints services deploy greetingv1openapi.json authedgreetingv1openapi.json 
result: Service Configuration [2019-01-07r9] uploaded for service [inner-cinema-211407.appspot.com]

update the app.yaml as following:

env_variables:
  # The following values are to be replaced by information from the output of
  # 'gcloud endpoints services deploy swagger.json' command.
  ENDPOINTS_SERVICE_NAME: inner-cinema-211407.appspot.com
  ENDPOINTS_SERVICE_VERSION: 2019-01-07r9

deploy to GAE

gcloud app deploy --project=inner-cinema-211407

I have a similar issue using Endpoints for Cloud Run (not python framework). I can deploy multiple yaml files using x-google-api-name, but portal only show the first one. APIs from both files are called, but I haven't tested authentication.
Issues could be related.
