What causes Fabric Copy Activity Error 20743?

The 'fileForbidden' property is set in skipErrorFile but the copy activity source is a single file rather than a folder. Copy activity is not using direct binary copy mode, making fileForbidden incompatible. skipErrorFile settings were bulk-applied from a template without verifying source configuration compatibility

Frequently asked questions

What does 'fileForbidden' in skipErrorFile actually do?

When properly configured, fileForbidden allows the copy activity to skip files that return access-denied or forbidden errors (e.g., files the service principal lacks permission to read), continuing the copy for other files in the folder.

Is error 20743 the same issue as error 20744?

They are related but distinct. Error 20743 occurs because the copy activity is not using direct binary copy with a folder source. Error 20744 occurs because the specific connector being used does not support the fileForbidden skip option at all.
