I've built a test API in a new Maven-based App Engine Standard project created in Eclipse. Upon adding API Management and deploying on production server, I get a 500 response when trying out the API on the Endpoints Portal. Error logs in the dashboard show the following exception:
endpoints.repackaged.com.google.api.config.ServiceConfigException:
Failed to fetch default config version for service 'networking-1088.appspot.com'.
No versions exist!
I checked out similar questions like this one but I have used the project ID as the service name consistently across files, have not included service version, and have used all the necessary boilerplate code from the documentation.
Below are relevant snippets from my files:

How can I get rid of this error while retaining API management?
