Sitecore 8.2 to Sitecore 9.1 Upgrade - Content Editor Error

I recently upgraded from Sitecore 8.2 Update 2 to Sitecore 9.1, using the Upgrade guide.

The site works correctly but in the Content Editor as well as Experience Editor, I get the following error in a pop-up while interacting with the items:

Exception of type 'System.Web.HttpUnhandledException' was thrown. | System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentNullException: Null ids are not allowed.
