Genesyscloud_messaging_application 409 on AU-1 BYOC

General Discussion

Is it possible to bypass the 409 Conflict when creating a messaging application via Terraform on AU-1 BYOC?

Env: AU-1 BYOC
Provider: genesyscloud 2.5.1
TF: 1.6.0
Resource: genesyscloud_messaging_application

Plan succeeds. Apply fails with 409. API trace shows duplicate external_id. Manual deletion not resolving state drift. HCL config matches previous working deploy. Any workaround for idempotent creation?

Thanks.
