#11 98.76 > transformers@1.4.4 build
#11 98.76 > babel --root-mode upward src --out-dir lib
#11 98.76 
#11 99.04 Error: Babel was run with rootMode:"upward" but a root could not be found when searching upward from "/app/packages/transformers".
#11 99.04 One of the following config files must be in the directory tree: "babel.config.js, babel.config.cjs, babel.config.mjs, babel.config.json".

Possible that the error comes from the fact the @ezs/transformers was in a monorepo, where the babel.config.js is at the root of the repo.
