How do I fix OpenAPI document generation on Google Cloud Endpoints?

问题

I am working through the tutorial: 'Getting Started with Cloud Endpoints Frameworks on App Engine Standard'. https://cloud.google.com/endpoints/docs/frameworks/python/get-started-frameworks-python

On step two of the 'Generating the OpenAPI document' section when running the command after having replaced 'MY_PROJECT_ID' with my project ID:

python lib/endpoints/endpointscfg.py get_openapi_spec main.EchoApi --hostname [MY_PROJECT_ID].appspot.com

I get the following error:

Traceback (most recent call last):
  File "lib/endpoints/endpointscfg.py", line 31, in <module>
    main(sys.argv)

endpoints.api_exceptions.ApiConfigurationError: audiences must be a dict when third-party issuers (auth0, firebase, etc) are in use.

Does anyone know how to address this?

thanks for using Cloud Endpoints Frameworks.

This is a bug that was introduced in Frameworks version 4.7.0. I've opened https://github.com/cloudendpoints/endpoints-python/issues/184 to track it and will try to have a fix out soon.
