All serverless functions return error 1101 on CF worker

[eliasbenbourenane]

Any serverless function I use returns error 1101 despite Cloudflare’s ‘Preview’ window displaying the output of my functions correctly. To test, I used Cloudflare’s “HTTP Handler” template, which I pasted below and simply returns “Hello World.” This also outputs error 1101.

export default {
  async fetch(request, env) {
    return new Response("Hello world")
  }
}

The URL of this CF worker is https://broken-heart-6120.eliasbenb.workers.dev
And, as you can see in the attached image, the page returns with status code 200 (atleast on the CF worker editor)

Any ideas? Thanks!
