Architect Data Action to trigger Common Module returns 400

Trying to call a shared flow from multiple inbound call flows using a Data Action, but it keeps failing with a 400 Bad Request.

  • Using genesyscloud_flow_dataaction in Terraform
  • Target flow ID is correct and published
  • Payload is empty JSON {}

Here is the config:

{
 "type": "flow",
 "flowId": "abc-123-def"
}

Getting "error": "Invalid flow reference". Anyone see this before?
