Lab 4.1: Failure creating worker nodes

Good day, please help me get over this issue. The command to create the 6 worker nodes returns "ERROR: (gcloud.compute.instances.create) Could not fetch resource:
- Request had insufficient authentication scopes."

This is a view of my screen:

[kamangafisher@aio1 ~]$ for i in 01 02 03 04 05 06; do INST_NAME="anod-worker-"$i; \

gcloud compute instances create $INST_NAME --zone us-central1-f \
--machine-type n1-standard-8 \
--image "https://www.googleapis.com/compute/v1/projects/onap-177920/\
global/images/aarna-anod-dublin-ubuntu18-04-08102020-00"; \
done
