WFM Schedule Resource 400 Error on Terraform Apply

Looking for advice on resolving a persistent 400 Bad Request error when applying genesyscloud_wfm_schedule resources. The provider logs indicate a validation failure on the segments array structure, specifically regarding the unit_of_measure. Environment details: Terraform 1.7.6, Genesys Cloud Provider v3.6.1, Region ap-southeast-1.

{
 "segments": [
 {
 "unit_of_measure": "hours",
 "value": 40,
 "type": "work"
 }
 ]
}

The payload appears valid against the OpenAPI spec. Is there a known issue with the provider’s serialization for WFM schedule segments?
