Crash Output

Expected Behavior

Ran terraform apply, knowing that the real resource already existed:

Error: Error applying plan:

1 error(s) occurred:

* google_compute_instance_group_manager.jenkins-nodes-terraform-2: 1 error(s) occurred:

* google_compute_instance_group_manager.jenkins-nodes-terraform-2: Error creating InstanceGroupManager: googleapi: Error 409: The resource 'projects/basekit-ci/zones/europe-west3-c/instanceGroupManagers/jenkins-nodes-terraform-2' already exists, alreadyExists

Ran terraform import, expecting the resource to be importted.

Actual Behavior

Crash

[jonathan@xps terraform]$ terraform import google_compute_instance_group_manager.jenkins-nodes-terraform-2 jenkins-nodes-terraform-2
google_compute_instance_group_manager.jenkins-nodes-terraform-2: Importing from ID "jenkins-nodes-terraform-2"...

Steps to Reproduce

Attempt to import an existing instance group manager

terraform init
terraform plan
terraform apply
terraform import google_compute_instance_group_manager.jenkins-nodes-terraform-2 jenkins-nodes-terraform-2

Additional Context

Running from command line. No customisation or anything weird.

Hey @djjudas21! Are you able to reproduce this issue with version 1.20.0 or 2.0.0 of the provider? 1.18.0 was a while ago, and I'd imagine this issue has been fixed since then although I can't recall any specific fixes offhand.

[djjudas21]

Ah sorry, I thought I was already on the latest provider before submitting the report as I re-ran terraform init but I just realised I need the -upgrade flag. I've now upgraded to 1.20.0 and yes the crash still occurs. I attempted to try 2.0.0 but my codebase isn't currently compatible.

[rileykarson]

I was unable to repro this, and we're 20 minor releases later and about to cut 3.0.0 in a week or two. Closing as outdated.
