azure-cli: Getting token from Cloud Shell intermittently fails with 400 Client Error: Bad Request

I’m getting following when I’m running following command :

ARM_CLIENT_SECRET=$(az ad sp create-for-rbac
–name http://tf-sp-$UNIQUE_ID
–role Contributor
–scopes “/subscriptions/$ARM_SUBSCRIPTION_ID”
–query password
–output tsv)

Please note that I’ve stored ARM Subscription ID successfully and ran above command as part of creating Service Principal.

This is autogenerated. Please review and update as needed.
