I made a change to backends.py and I’m trying to upload the project and am getting an error. I have used the rollback command as well but I keep getting the error.
Error 409: --- begin server output ---
Another transaction by user admin is already in progress for app: s~test-appx,
backend: urlstat. That user can undo the transaction with "appcfg backends rollback".
--- end server output ---
Does anyone have any idea about this?
This happens on occasion when something terrible happens during a push. If you wait long enough, it will eventually time out and you will be able to update normally again.
The lock is specific to a version of your application. So, if time is short, you can work around this error by pushing to a different version, and then making it the default from the appspot.com dashboard.
The
-Vflag allows you to specify which version to target.
