builder error when deploying to App Engine

[Tyler Ishikawa]

Up until around the beginning of the month, my Django app was working fine, but all of a sudden, it started sending 500 Internal Server Error on one of the endpoints. When I tried to update the app by deploying a new version, I received a builder error (exact error pasted in the attached file).

When I create a new GCloud project and deploy the exact app to that project, it deploys fine (although the 500 Internal Server Error is still there).

What can I do to fix this deployment error? Can I somehow "delete" the App Engine service and redeploy it? I don't want to delete the whole GCloud project because I would like to keep the appspot.com domain name. Thanks in advance.

The 500 Internal errors may be related to a known issue so please specify the time as exact as possible when creating an issue tracker as this issue will likely need further investigation. It is unclear the cause of the of the builder error so please include in the issue tracker if you are using Cloud Build and if so how it is deploying App Engine(perhaps by using Cloud Source Repositories etc) and your use case as it is unclear why the deployment error is occurring. 

To delete an App Engine service using the below gcloud command, however as there is a deployment error deleting the currently one is not recommended until we take a look at the issue. 

gcloud app services delete SERVICES [SERVICES …] [--version=VERSION]
