Genesys Cloud Digital Channel 409 Conflict on Terraform Apply

Just noticed that applying a new digital channel configuration fails with a 409 Conflict. The channel exists in the UI but Terraform claims it is missing or conflicting.

  1. Define genesyscloud_routing_email_domain resource in HCL.
  2. Run terraform apply with provider v1.65.2.
  3. Receive 409 error: “Resource already exists”.

Environment: Terraform v1.9.8, Region: Australia/Sydney. How do I import or resolve this state drift for Digital/Messaging resources?
