E1665137590 Source and destination data sources do not have the same number of headers


This error can happen when cloning a custom report containing a Join data source. It indicates that either of the two data sources joined by the Join data source have since had headers added or removed.

Therefore, the Join data source is out of date and can’t be cloned.

Help me resolve this

Edit any field of the Join data source (e.g. “Title”) and resave it. You should then be able to clone the custom report successfully.
