The script currently generates a configuration which convert units like millimetre and centimetre to themselves (with a factor of 1) rather than to multiples of metre with the appropriate factor. Presumably something changed in the Wikidata data model, and we need to adjust the SPARQL queries in the script.
This can be tested locally, without production access – run php repo/maintenance/updateUnits.php --sparql https://query.wikidata.org/sparql and it’ll pull all its information from there.

Hm, it looks like the script basically does the right thing if you call it differently: instead of --base-unit-types Q223662,Q208469 as the comment at the top of the script suggests (SI base unit, SI derived unit), use --base-unit-types Q69197847 (coherent SI unit).
That said, I think the script should still be updated to not use the term “base unit” when it actually means “coherent unit”.
