Debug Output

Panic Output

https://gist.github.com/brettaukburg/7ef24d9d8ff70b58bc42c9708e640944

Expected Behavior

I expected the "terraform destroy -parallelism=200" to remove all the resources that I had built with Terraform.

Actual Behavior

Terraform panics instead of executing any of the destroy.

Steps to Reproduce

1. terraform apply -parallelism=200
2. wait for build to complete (in this case, there were Azure errors due to subscription limits so not all resources could be created)
3. terraform destroy -parallelism=200

Important Factoids

Running in Azure
The subscription had a limit of 800 VMs which stopped the original apply
