I deleted by accident project-id.appspot.com, us.artifacts.project-id.appspot.com and staging.project-id.appspot.com buckets created by cloud scheduler and now it stopped to work. I can't redeploy again, I can't recreate the buckets because its ended in appspot.com (because I need domain verification for that, and of course appspot.com isn't mine.)
How to recovery?
I think you should run the command :
gcloud beta app repair
(BETA) For example, this command will restore the App Engine staging bucket if it has been deleted. It will no longer restore the service account, instead, the IAM service account undelete API must be used for the purpose.
gcloud beta app repair - restores required App Engine features to the current application
