Usually 'Error code 204' relates to an issue in the appserver, so its possible it was caused by ApiProxy$UnknownException as it was thrown in package com.google.apphosting.runtime. If you still see these errors, you might try deploying to a new version. Otherwise you might want to report this on the Issue Tracker <https://cloud.google.com/support/docs/issue-trackers>.
