Google App Engine Fix “Another transaction by user acct is already in progress”

If an update for Google App Engine doesn’t complete it will cause an error and not allow you to upload new updates the error code is similar to: Another transaction by user acct is already in progress for this app and major version. That user can undo the transaction with appcfg.py’s “rollback” command.

Rollback Google App Update

Yes this has helped me–the script didn’t work because of a deprecation error, but the basic idea was very helpful. Thank you for writing this post!:-)

Another way to fix this is incrementing the version number in your app.yaml file. Maybe not the prettiest solution, but faster

  Yes this will work, but you will need to set that version to be active, in the online section
