History of Pages Stopped

The pages have stopped showing the history. I haven’t changed any configuration
If I check the source of the page and clicked show last authors I’m getting

Failed to execute template. Cause: [Cannot invoke “com.xpn.xwiki.doc.rcs.XWikiRCSNodeInfo.getId()” because “this.nodeInfo” is null]. Click on this message for details.

In my page, in the History section I’m getting

“Warning:There is no history to show”

Is there any way to overcome it?

Hello. What version of XWiki is this?

Also, please click on the “Click on this message for details.” link and paste the details.

Thanks

Version is 14.10.14

It’s not showing anything like click on this message for details, it’s not showing like a error message more like a warning message

If I go to source and click on the show last authors is giving an error

Failed to execute template. Cause: [Cannot invoke “com.xpn.xwiki.doc.rcs.XWikiRCSNodeInfo.getId()” because “this.nodeInfo” is null]. Click on this message for details.
