create a brand new sveltekit app from command line

create an api route with POST request create a +page.svelte in a normal route in src , in there you upload file to api route using fetch with post method. it will fail.

Can you provide a repository with a minimal demo app? @craigcosmo

@craigcosmo In your reproduction, in file /src/lib/config.ts, doesn't look like you updated the dev urls:

let apiUrl: string =
  env == 'production'
  ? 'https://contron.vn/api/'
  : 'http://localhost:2233/api/'

Changing the dev url to 'http://localhost:9955/api/' gave me a success message.

I mean it works on localhost, but not on any server, whether it's vercel or render.com

When I switched back to node apdater, the upload worked on servers.

@craigcosmo, the origin checking has been changed lately, could you test if it still fails?

[applemate]

This happened before the origin checking

My hypothesis is that origin-checking is not the issue, but more that there were problems with how Bun handled requests. In Bun 1.1.27 they seemed to have fixed it, so after upgrading Bun, I'd be curious if the problem remains.
