Describe the bug

I've tried Clerk Webhooks on localhost with success (API Route). When published on Netlify I'm getting this error (not related to webook validation or secretes):

without any code we are not able to investigate

I see. But this is part of a big code base and it is hard to replicate just that part.
Anyway it seams to be ssr.mjs trying to write in a non existing folder after deployment.

I've just upgraded to 1.131.35 and have a similar issue on Vercel. https://personal-space-git-upgrade-tanstack-ugzuzgs-projects.vercel.app/en/climbing

This appears to have been addressed by #6940. The static server function cache no longer attempts to write into the build output during normal production runtime, which matches the /opt/build and /vercel failures reported here.

Could either of you retry this with the current Start version and confirm? I haven't reproduced the original Netlify or Vercel deployment itself, but if you can reproduce this on a current version of Start can you open a new issue with a repro?
