Error invalid instance URLs: resource “google_compute_instance_group” “t-compute-instance-group”
Goal : Create a compute instance and add it to an unmanaged instance group in GCP using terraform.
Issue : A compute instance and an unmanaged instance group are being created successfully, but the instance is not being added to the group and giving: Error invalid instance URLs: resource “google_compute_instance_group” "t-compute-instance-group"
Able to add the instance to the group manually after running the terraform configuration though.
