Error in the pending changes webtree ver 2.1.22

Hello, after editing the site by one of the site users who had the role of editor on the site. When I logged in as an administrator, I saw the following error. After confirming the pending changes, the error was fixed. What is the reason?

With pending changes, we keep a copy of the old and new data.

When we create new records, the "old" data is NULL.
When we delete records, the "new" data is NULL.

It shouldn't be possible for both "old" and "new" to be NULL at the same time.
But if they are, then it would give the error that you see.

I can't think of any explanation for how this has happened on your site.

Can your editor give any extra information?

thanks Unfortunately, I could not understand anything about the editor and the type of operation. In the subsequent changes that were made in the information, this has not happened again
