Proxy with Angular 17

[tagazok]

Describe the bug

Hi,

I have a project that works perfectly with Angular 16 and webcontainers.io However, I just uplated the project to Angular 17 and it doesn't work anymore.

This is the error I have:

[vite] http proxy error: Must provide a proper URL as target
Error: Must provide a proper URL as target

This may be due to Angular moving from webpack to vite but I didn't figure out how to fix the issue. I don't have the issue if I remove the proxy configuration but then webcontainers doesn't work anymore because of "SharedArrayBuffers" issue

Here is my proxy confitguration in my angular.json (it hasn't changed when updating the project from Angular 16 to Angular 17)

"options": {
    "headers": {
      "Cross-Origin-Embedder-Policy": "require-corp",
      "Cross-Origin-Opener-Policy": "same-origin"
    }
  }
