Genesyscloud_flow 400 on agent_script resource import

Encountering a 400 Bad Request when attempting to import an existing Agent Script into Terraform state.

Error: error importing genesyscloud_flow: 400 Bad Request
Details: Unable to parse flow definition. Missing required field: 'type'.

Provider: 1.15.0
Region: apac-1

The script exists in the UI. Standard flow imports work fine. Is the Agent Script resource type not yet supported for import via the CLI, or is there a specific syntax required for the import block?
