Terraform 500 on BYOC Edge Config via API

Why does this setting trigger a 500 internal server error? trying to push BYOC edge configuration via terraform.

env: us-1 prod
provider: genesys 1.15.4
tf: 1.6.5

the error is

POST /api/v2/platform/byoc/edges returns "Internal Server Error"

Note: BYOC edge resources require manual provisioning before API configuration.

config:

resource "genesyscloud_byoc_edge" "main" {
 name = "prod-edge"
}
