Is it possible to automate AI Agent provisioning via Terraform on AU-1 BYOC without hitting validation loops?

Applying genesyscloud_ai_agent fails with 422 Unprocessable Entity. The API rejects the initial_prompt configuration despite valid JSON structure in the HCL module.

Environment is Terraform 1.8.5 with provider 1.52.0. Any known schema restrictions for BYOC analytics reporting integrations?
