sh: 1: build-storybook: not found
This is occurring on all repos that use storybook: Minerva, Vector blocking merges.
Example: https://gerrit.wikimedia.org/r/c/mediawiki/skins/Vector/+/730858
It was working fine early today, works fine locally (although haven't tested with fresh). It was working yesterday so something has likely changed upstream.
Unbreak now because it's blocking a train blocker.
