SetLabel Error: Calling principal is forbidden to perform the operation

[dawei-medaitek]

as title, I run below code , when the labelId is a label bind Protection , error occured at commonAsync : Calling principal is forbidden to perform the operation; if labelId is a label with no protect , it works~

code: handler.SetLabel(fileEngine.GetLabelById(labelId), labelingOptions, new ProtectionSettings()); var result = Task.Run(async () => await handler.CommitAsync(outputFilePath)).Result; // error occured~
