This issue had previously been reported in Public issue Tracker <https://issuetracker.google.com/72070652> and is already being looked into by the engineering team. You could star the case to receive any updates on the fix. It seems that this issue is a result of Icon files <https://issuetracker.google.com/72070652#comment10>. So, as a workaround I recommend that you delete these files.
I should note that the Public Issue Tracker <https://cloud.google.com/support/docs/issue-trackers> is for reporting Google Cloud-end issues and feature requests. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
