Data Action 409 Conflict on Webhook Update via Terraform

Quick question about Genesys Cloud Data Actions. Pushing a simple webhook URL change via Terraform (provider 1.15.4) triggers a 409 Conflict. The API response indicates the resource is locked or in use, but no flows are active.

PUT /api/v2/integrations/dataactions/webhooks
409 Conflict: Resource is currently in use by an active flow or deployment.

How do I bypass this lock or identify the hidden dependency blocking the update?
