Netlify briefly broke esbuild builds, causing "Dynamic require of "X"" errors for every serverless rendered page [fixed]

Describe the bug

as part of regular maintenance for swyxkit i upgraded the deps as per the title

and now everything is throwing a 500 error with this Dynamic require of "fs" error, even though i’m pretty darn sure I don’t actually write that code. EDIT: Possible related error: https://github.com/sveltejs/kit/issues/2400

this error only happens in prod build, not in local dev. is this something broken in the netlify adapter?

WOW so it was not my/our fault?!? amazing. thank you so much, will retry.

edit: confirmed that a simple rebuild fixed it, now that Netlify reverted their change. watch https://github.com/netlify/zip-it-and-ship-it/issues/1036 for when they try it again.
