Our deployments for the default module for a specific application do not seem to work randomly, at least in 50% of cases, which constantly disrupts our workflow.
With verbose logging enabled through appcfg.py update app.yaml --verbose, this error appears on the terminal:

The request is invalid for an unspecified reason.

The failure is very consistent, because in most cases we try to deploy the module after it has not been deployed for several hours, the deployment attempt will fail with the output above.
