Topic on Talk:MediaWiki 1.39

I updated from version 1.33.0 to version 1.39.3 and I have this error:

Original exception: [21dbfcdc763b93fdb3cf967d] /index.php/Accueil MediaWiki\Revision\RevisionAccessException: Main slot of revision not found in database. See T212428.

What can I do to fix it? All clues found on the web are for older versions.

I believe that running php maintenance/findBadBlobs.php should still help, but that advice might be out of date as you say.
