    Description

      Steps to reproduce

      1. Create a subwiki (I've created a subwiki named subwikiglobal2 with 'Both global and local users are available in the wiki')
      2. Create a local user on the subwiki
      3. Login with the local user
      4. Follow the entire wiki (on a page, click on Notifications button, select 'Follow entire wiki' and Save)
      5. Login with Admin
      6. Edit a page (e.g. Sandbox) on the subwiki, add a word and Save
      7. Go to Job Scheduler (<server>xwiki/bin/view/Scheduler) on the subwiki as well
      8. Trigger the 'Notifications daily email' job

      Expected results

      No warning is displayed in XWiki logs.

      Actual results

      The following warning is displayed in XWiki console:

      The warning was also reproduced on XWiki 18.6.0, 18.4.3, 17.10.11 and 17.10.3, but it seems it couldn't be reproduced on XWiki 16.10.18 or 16.10.3.
