This issue started with vite 5.2.0, but only seems to affect (some) sveltekit users

[buhodev]

I had the same issue. It's vite's fault in my case. I downgraded to v5.1.6 and it worked.

[IggyCeltic]

It does look like downgrading to vite 5.1.6 might be fixing it for me as well.

Downgrading to adapter-cloudflare 4.1.0 seems to be fixing it

The relevant Vite issue -> vitejs/vite#16245

[ZerdoX-x]

I spent several hours debugging, this is the change that caused the issue: vitejs/vite#16135
Introduced in vite@5.2.0-beta.1
vite@5.2.0-beta.0 works fine

In my case vite breaks @inlang/paraglide-js-adapter-sveltekit, without it, in clean project, all works fine.

I added a repro to the ticket: vitejs/vite#16245 (comment)

[patak-dev]

Sorry for the regression, it will be fixed by vitejs/vite#16246. I'll cut a release tomorrow

The fix has been released in Vite 5.2.5. Thanks Matias.
