Support SvelteKit Vercel Adapter (without Edge Runtime)

[Lms24]

In a first step to fully support SvelteKit apps deployed on Vercel, we should add support for @sveltejs/adapter-vercel.

The first step here is to add a working configuration for uploading source maps and making everything work for lambda functions. This doesn not yet include support for the edge runtime as this requires some more changes in the monorepo (extracting the edge SDK, bundling changes) first.

Happy to beta test if it's helpful!

Hi @wtachau we're releasing 7.54.0 in a few minutes. Feel free to let us know if you want to try it out and encountered issues.

thanks @Lms24! Other than the issue you already responded to here, I see a number of these warnings in the Vercel build:

- warning: could not determine a source map reference (Could not auto-detect referenced sourcemap for ~/chunks/index.js.map)
--
11:39:27.945 | ~/chunks/index2.js (sourcemap at index2.js.map)

What's a good way to try and debug this?

@wtachau thanks for reporting!

I just checked and for me, these files resolve with correct source maps when deploying to vercel.

14:59:29.576 | ~/chunks/index.js (sourcemap at index.js.map)
14:59:29.576 | ~/chunks/index2.js (sourcemap at index2.js.map)
14:59:29.577 | ~/chunks/index3.js (sourcemap at index3.js.map)

Which adapter are you using and do you have any specific adapter settings?

Since I'm on vacation for the next two weeks, would you mind opening a new issue so that my colleagues can pick it up and triage? Ideally, you could provide us a minimal reproduction example which we can use to debug. Thank you!

I'm going to close this issue in the meantime.
