BYOC Edge Registration 400 - Invalid Certificate Format via Terraform

Need some help troubleshooting BYOC edge registration.

Context: Terraform v1.9.8, Genesys Provider v1.65.0. Region: ap-southeast-2. Pushing genesyscloud_byoc_edge resource.

Question: Apply fails with 400 Bad Request. Error message: “Invalid edge certificate format”. Certificate is PEM encoded. Private key matches. OpenAPI spec says format is correct. Does provider strip newlines? Is there a specific header requirement for BYOC endpoints?
