After upgrading to 8.x-1.1, any visit to a term's "Revisions" tab that has revisions attributed to "Anonymous" results in the following warning (showing up on the page and the dblog, once for each such "Anonymous" revision, so sometimes multiple times):
Warning: array_flip(): Can only flip STRING and INTEGER values! in Drupal\Core\Entity\EntityStorageBase->loadMultiple() (line 312 of core/lib/Drupal/Core/Entity/EntityStorageBase.php).

I don't know the full history of how/why the site has term revisions claiming to be by "Anonymous", but let me know if I can provide other info, or test potential patches/changes (which I don't have bandwidth to work on), since I realize it might be non-trivial to reproduce this condition. Thanks!

It's likely this issue predates Contrib.social: some issue and comment data are missing.
@jamie.slater Your code worked for me too. I added a patch against the 8.x-1.1 tag as the 8.x-1.x branch was not up to date with the tag.
This issue is fixed in 8.x-1.x branch. @maxstarkenburg, @introfini, @jamie.slater and @philltran thank you for the support.
