“Missing issuer google_id_token” when generating OpenApi doc for Cloud Endpoints with Auth0

Question

I'm creating an app backend with GAE Standard Environment and Cloud Endpoints in Python that needs to be able to authenticate via Auth0.

I have included an "issuers" object in the API decorator (https://cloud.google.com/endpoints/docs/frameworks/python/authenticating-users#authenticating_with_auth0).

I have also set up an Auth0 account and have set up a "Regular Web Application" that is referenced in the issuers object and have included the following libraries in my project directory: google-endpoints 4.4.0 and google-endpoints-api-management 1.9.1

When I attempt to generate the OpenApi document (https://cloud.google.com/endpoints/docs/frameworks/python/adding-api-management), I get the following error: "TypeError: Missing issuer google_id_token".

Any advice as to how to properly generate an OpenApi document for Cloud Endpoints in Python that incorporates Auth0?

Answer 1

You have passed a list or tuple for audiences somewhere in your code. When you do this, Endpoints assumes there will be an issuer named google_id_token. (This is for backwards compatibility reasons.) If you wish to use issuers with other names, you need to pass a dict as audiences; for example: audiences={"auth0": ["aud-1.auth0.com", "aud-2.auth0.com"]}.
