I'm using appcfg.py to update my app as usual, and I'm getting an error message. I've tried appcfg.py rollback, and I've waited ten minutes between attempts but I still get the same error message. What should I do?
cannot operate on apps/devnpfieldapp2/services/default/versions/1 because an operation is already in progress for 9866bb4e-75de-4a2a-a9f6-891ad7fe724e by 5a972249-5b35-45e0-abd1-ac3554ec425b.

I recommend to upgrade your Cloud SDK to the latest version by running “gcloud components update” command and retry the upload. If the issue persists, you can report it to the Issue Tracker and provide us with the output of the command you are using to deploy your app with “--noisy” flag so that we would be able to dig into the issue.
It is also recommended to use gcloud command Line equivalents to deploy apps since it is easier to debug.

I had the same issue on CI but solved it by running the deploy command locally first, and then running it again on CI.
