Error code

Details

This error occurs when a SharePoint object refers to a view which cannot be found either at the source or destination site. This error might happens when copying User alerts, Nintex forms or calendar views.

Solution

Make sure the selected view is available for the list. If it is not available at the source, this means it might have been deleted after the object was created. You can simply modified the view which the object is referring to. If you recreate it, you will still need to select the newly created view in the object edit page. If it is not available at the destination, make sure you have migrated it first then retry the migration.
