Workflow Data Fabric – "Failed to Reserve Data Fabric Engine" Error - Support and Troubleshooting

Workflow Data Fabric – "Failed to Reserve Data Fabric Engine" Error Issue:

When attempting to use the Workflow Data Fabric (WDF) Zero Copy Connector, the following error is encountered: "Failed to reserve data fabric engine"

Root Cause: This issue typically occurs when the instance purpose is set to something other than prod or subprod . Instances with purposes such as demo are not allowed to reserve the Data Fabric engine. This restriction is in place to protect backend capacity.

The provisioning rules explicitly block demo instances from initiating the backend WDF provisioning (Trino), resulting in the failure of the reservation.

Solution: Ensure the instance purpose is set to either:

prod subprod If the instance is intended for production-level operations or pre-production testing, change the instance purpose appropriately.
