WebChat Widget Config Sync Failure via Terraform

Could someone explain the validation error when deploying WebChat widget configuration using the genesyscloud_widget resource? The Terraform apply fails with Error creating widget: 400 Bad Request and the response body indicates invalid widget configuration. The environment is Genesys Cloud Production (EU-West-1), provider version 1.38.0. The HCL block defines the web_chat settings with a valid skill reference and queue ID. Debug logs show the CLI successfully authenticates, but the API rejects the web_chat payload specifically. The error message does not specify which field is malformed. I have verified the queue exists and is not paused. The skill is active. Other widget types like callback deploy without issue. Is there a known schema mismatch in the provider for web_chat specific attributes? Or is the API requiring additional metadata not documented in the HCL resource? The deployment pipeline uses GitHub Actions with standard OIDC authentication. The failure happens consistently on every run. Manual creation via UI works, but the JSON export from UI does not match the Terraform structure. Looking for insight on the specific attribute causing the 400 error.
