ah this was in a railway.json, my bad can you send your build logs that use the v2 builder please - https://bookmarklets.up.railway.app/log-downloader/

Brody•4w ago

and just for clarity this all works on the legacy builder and your custom phase shows up in the build table?

Michael Li•4w ago

yes, for v1. i can see there are npm config command runs after COPY . /app/.

Brody•4w ago

okay, thank you very much I will forward this thread to the developer that is working on the v2 builder
