Migration trouble related to DiscourseJsProcessor?

It’s production. It’s got traefiks as a reverse proxy, but it’s pretty much a standard install other than that (and a database built from the standard postgres13 image, but it does have pgvector).

I mentioned my dev environment because I did a git pull there trying to see if the commit had hit tests-passed; I do see FIX: Compile js-processor before db:migrate (#23229) in git log there).

I’ll go back to testing what I was testing before and try again in a bit.
