Terraform import genesyscloud_routing_queue hangs on state pull

Trying to import an existing queue into Terraform state using the standard terraform import command. The CLI connects fine, but it just hangs after printing the import id. No error, just a cursor blinking in Berlin time.

terraform import genesyscloud_routing_queue.main 8b5c2d1e-4a3b-4c5d-9e0f-1a2b3c4d5e6f

The queue exists in the UI, I can GET it via /api/v2//queues/8b5c2d1e-4a3b-4c5d-9e0f-1a2b3c4d5e6f without issues. The provider version is 1.12.0. Running terraform plan after the hang (if I manage to ctrl+c) shows the queue as needing creation because it’s not in state. Is the import logic broken for queues with active members or am I missing a flag?
