Updating drupal core from 10.1.1 to 10.1.2 breaks Unami site

Umami is experimental and meant for demo use only, we have never intended to support upgrades between versions for sites using it.

See https://www.drupal.org/docs/getting-started/umami-drupal-demonstration-i... →

We may also make changes that break your current install

Leaving this open for now for other committers to comment; to me this is works as designed and while we could start adding update hooks to Umami I think we only ever intended it to be installed on a single version.

Totally agreed @longwave, but the flip side is the entire ecosystem has become dependent on Umami because it's so great for demo environments. We all use it like crazy for everything. Maybe it's so very good that it should be promoted from experimental. Obviously it's not for production, but that doesn't mean it's not as valuable as something that should be for production.

Umami maintainer here!

I'm fine with this being closed as "Works as designed" as we are perpetually experimental and not providing updates.

However, to fix the issue reported, I reckon you can simple install the SDC (Single Directory Components) module that is available (also experiemental for now) from Drupal 10.1. Can you check if that fixes your issue please?
