Hello Railway Team 
I’m running several Bun Functions (using the official image ghcr.io/railwayapp/function-bun:1.3.0).
Since a few days ago, my functions started crashing with the following error:
error: Cannot find package 'tslib' from '/app/node_modules/@supabase/functions-js/dist/main/FunctionsClient.js'
This never happened before — same code and package.json were working fine previously.
It looks like the new Bun runtime no longer includes tslib resolution for dependencies like @supabase/functions-js (used by @supabase/supabase-js). Since Railway Functions are sandboxed, I can’t patch node_modules or add symlinks manually.
Could you please confirm if something changed in the Function build/runtime environment for Bun, or if there’s a new recommended way to include tslib globally?
Thank you

Hi there! Let me raise to the Bun team and see if they have any input.

I believe supabase should have fixed this now, so make sure you are using 2.76.1!
