ESP Test Quota at OpenApi document

Prerequisites to test it

  1. Create a Google Cloud Platform Project and specify get ProjectId. Specify ProjectId at host property in echoApi/spec.yaml and docker-compose.yml in services.esp.command as --service value. The projectId in this example was example-project-317294.appspot.com.

  2. Create a service account for ESP and save service account json file to credentials/service-account.json.

  3. Grant permissions to a client with api key and access-token, create an .env file based on .env.tpl and provide credentials.

Issue

The quotas is per minute, so if we get status code 429 Too Many Request and we wait a minute we should be fine but after we wait a minute the next request has status code 429, it happens even if we wait more than twice like 150 seconds. This repo reproduce the error. If see github action workflow run, there is one waiting 61 seconds with the issue and other waiting 150 with the same issue, also it happens to ESP and ESPv2.

Logs waiting 61 seconds

Github actions logs, for esp v1 we can see the issue here and for esp v2 we can see the issue here
