Quotas for Endpoint framework v2 in development environment and deployed project - google-app-engine

Question

Symptom:
I have a new standard environment endpoint framework (v2) project that works on the development server but when deployed to GCP the response is: This application is temporarily over its serving quota. Please try again later.
However if I try to add quota limits and metrics (as per https://cloud.google.com/endpoints/docs/frameworks/quotas-configure) the development server errors with: AttributeError: 'tuple' object has no attribute 'metric_name'.
The the full error logged is below. I suspect the warning about oauth2client is not relevant to the quota problem but is related to the current endpoints module.
The error seems to point to the limit_definitions but these are from the Google example.
Code snippet:
quota_limits = [
("read-requests", "Read Requests", 1000),
("list-requests", "List Requests", 100),
("write-requests", "Write Requests", 50),
]
#endpoints.api(
name='echo',
version='v1',
limit_definitions=quota_limits,
Question:
How can I either: not use quotas or correctly configure quotas? Or is there a bug?

Answer 1

quota_limits needs to be a list of endpoints.api_config.LimitDefinition instances, not a list of tuples. This is an error in the docs; I'll make sure they're corrected, and I'll improve the error message to be more clear.
