SolidStart Vercel deployment issue with CSR

Hi !

When I go to the website page, it just downloads the HTML with no file extension, nothing is shown in the browser.

When I go to

/__nitro

/__nitro

/__nitro

/__nitro though, I can see stuff but nothing shows up too, probably because I don't handle 404 yet.

Here's my vite configuration :

export default defineConfig({
  start: {
    ssr: false,
    server: { preset: "vercel" }
  }
})

export default defineConfig({
  start: {
    ssr: false,
    server: { preset: "vercel" }
  }
})

export default defineConfig({
  start: {
    ssr: false,
    server: { preset: "vercel" }
  }
})

export default defineConfig({
  start: {
    ssr: false,
    server: { preset: "vercel" }
  }
})

And you can even find the repository here https://github.com/Vexcited/Signatures-IUT-Limoges/tree/main/packages/website

Is there an issue with my configuration or another issue with CSR ?
