解決策

The workaround is deleting workbooks with multiple views with the same name in the destination server.

Error occurs when there are workbooks with multiple views with the same name exist on the destination server.
Ideally, a workbook will never have views with the same name. The multiple views issue can occur in test servers or when content doesn't get deleted properly.
