On one of my self-hosted Discourse, (fully up to date `docker_manager` and a docker image only a few weeks old ) I just ran in this error upgrading. I don’t know what version the site was on before, but it was only about 30 commits behind on tests-passed.

The site seems to be fine & responding, but I figured I’d mention something before I `./launcher rebuild app`
PS no, this isn’t the site I mess with server.en.yml, it’s just plain Discourse
