I am getting various other errors all over the place with moved pages (and the old pages), not related to wikibase or lua:

No valid null revision produced in Title::moveToInternal

Let's figure out if this bug is related to, a consequence of, or separate from bug 46397.

still getting errors

need to investigate more, see if I can reproduce it on master, etc.

this bug still happens if I remove all the wikidata lua stuff and just do a basic "hello world" lua script.

moving this to scribunto, although I am guessing it's core-related and could be filed under core.

(In reply to comment #5)

be
filed under core.

It's definitely core. The exception you're getting, "LinkCache doesn't know redirect status of this title", is thrown from core Title.php, in isRedirect(). Apparently something (possibly bug 46397) rebroke bug 37209.

It's just that Scribunto is what is happening to call isRedirect().

I couldn't reproduce after the bug 46397 fixes, but at least once person can (Greg).

Fixed with a revert in https://gerrit.wikimedia.org/r/#/c/55391/.

Closed older resolved bugs as verified.
