Hello Ergo,
I tried the command above as an owner of a project, and I was not able to reproduce the error message. Before trying the command again, I suggest verifying if your account is authenticated through the SDK by using [1] :
gcloud auth list If not authenticated, try [2] :
gcloud auth login [account]If this didn’t resolve the issue, I suggest opening a private issue tracker linking to this thread. Opening the report, please include the project ID, and URL map name, and we will be happy to assist.
