Issue is https://github.com/google/cloud-forensics-utils/blob/e010499745273e10bda3f030c734a3469c0a0296/tools/az_cli.py#L46 then https://github.com/google/cloud-forensics-utils/blob/e010499745273e10bda3f030c734a3469c0a0296/tools/az_cli.py#L48 where it trys to format the instance object rather than the instance name (compare to similar in the GCP provider).
