Terraform export command fails with 400 bad request on presence config

Need some help troubleshooting CX as code export for disaster recovery. running genesyscloud provider v1.35.0 from eu-west-1. the export command works for routing but crashes on presence config with a 400 error. here is the snippet:

resource "genesyscloud_presence_definition" "main" {
 name = "DR-Export"
 # fails here
}

the api docs say presence requires specific enum values but the terraform state shows null for the color field. anyone have a workaround for this?
