The Links / REFCACHE updates? check failure includes this output:

...

Attempting to run that locally eventually fails for me:

Attempting to run that [npm run test-and-fix] locally eventually fails for me:

This was "resolved" by manually deleting themes/docsy/node_modules, which I guess had incompatible content, then re-running npm install at the top-level. /shrug
