What causes Fabric Copy Activity Error 20744?

The connector specified in the copy activity source or sink does not support the fileForbidden skip error file option. A skipErrorFile configuration was applied globally or via template without checking connector-level support. The pipeline was migrated from a connector that supported fileForbidden to one that does not

How do I fix Fabric Copy Activity Error 20744?

Step 1: Identify the connector name referenced in the error message (the '%connectorName%' value in the error).. Step 2: Check the Microsoft Fabric Data Factory connector documentation to confirm whether fileForbidden is supported for that connector.. Step 3: Open the copy activity payload and remove the 'fileForbidden' property from the skipErrorFile configuration.. Step 4: If skipping forbidden files is a hard requirement, evaluate whether an alternative connector that supports this feature can be used for the same data source.. Step 5: Save and re-run the pipeline to confirm the error is resolved.

Frequently asked questions

How do I know which connectors support the fileForbidden skip option?

Refer to the official Microsoft Fabric Data Factory connector documentation for each connector. The supported fault-tolerance options including skipErrorFile properties are listed per connector. Not all connectors implement the full set of skip behaviors.

Is error 20744 different from error 20743?

Yes. Error 20743 means the copy activity settings (mode or source type) don't support fileForbidden. Error 20744 means the connector itself doesn't support fileForbidden, regardless of how the copy activity is configured.
