| Description: |
Steps to reproduce
- Create a subwiki (I've created a subwiki named subwikiglobal2 with 'Both global and local users are available in the wiki')
- Create a local user on the subwiki
- Login with the local user
- Follow the entire wiki (on a page, click on Notifications button, select 'Follow entire wiki' and Save)
- Login with Admin
- Edit a page (e.g. Sandbox) on the subwiki, add a word and Save
- Go to Job Scheduler (<server>xwiki/bin/view/Scheduler) on the subwiki as well
- 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. |
