Cannot permanently delete a running instance

[VJalili]

When I click the Archive/Delete button in front of a running instance, then choose the Delete Permanently and Archive option, I get the following error:

UNABLE TO CHECK STATUS Delete task failed: CloudBridgeBaseException: <HttpError 400 when requesting https://compute.googleapis.com/compute/v1/projects/<PROJECT_NAME>/zones/us-central1-b/instances/https%3A%2F%2Fwww.googleapis.com%2Fcompute%2Fv1%2Fprojects%2F<PROJECT_NAME>%2Fzones%2Fus-central1-b%2Finstances%2F<...>?alt=json returned "Invalid value 'https://www.googleapis.com/compute/v1/projects/<...>/zones/us-central1-b/instances/<...>'. Values must match the following regular expression: 'a-z?|[1-9][0-9]{0,19}'"> from exception type: <class 'googleapiclient.errors.HttpError'>

And on another instance I get the following:

Delete task failed: CloudBridgeBaseException: Unable to locate credentials from exception type: <class 'botocore.exceptions.NoCredentialsError'>
