Agent Scripting 422 Error During Terraform Apply in AU-1 BYOC

I’m trying to figure out why the genesyscloud_flow resource fails during automated deployment. The plan succeeds, but apply returns a 422 Unprocessable Entity on the scripting node configuration.

Running Terraform provider version 1.3.1 in AU-1 BYOC. GitHub Actions workflow triggers the apply. The HCL syntax validates locally without issues.

The error points specifically to the initial_action block within the flow definition. No clear documentation exists for this specific constraint in the BYOC environment.

Has anyone successfully deployed complex agent scripting flows via IaC in this region? Looking for examples of valid HCL structure for scripting nodes.
