!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Terraform crashed! This is always indicative of a bug within Terraform.
A crash log has been placed at "crash.log" relative to your current
working directory. It would be immensely helpful if you could please
report the crash with Terraform[1] so that we can fix this.

When reporting bugs, please include your terraform version. That
information is available on the first line of crash.log. You can also
get it by running 'terraform --version' on the command line.

!!!!!!!!!!!!!!!!!!!!!!!!!!! TERRAFORM CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Crash log: crash.log.gz

Expected Behavior

Actual Behavior

Steps to Reproduce

1. I've created peering manually in Azure.
2. I've tried to import it via terraform import azurerm_virtual_network_peering.peerUKSnm2UKSouth /subscriptions/6fc88d09-cfee-4f23-yyy-xxx/resourceGroups/foo/providers/Microsoft.Network/virtualNetworks/uk_south, but I had the error: Error: rpc error: code = Unavailable desc = transport is closing.
3. So I've retried again, I had Error: rpc error: code = Unavailable desc = transport is closing error again, but this time Terraform crashed.
