Worker is not resizing

Hello, I have created worker, by copy pasting the example bellow https://developers.cloudflare.com/images/image-resizing/resize-with-workers/#an-example-worker However I have noticed on requests it keeps the quality to 100, how can I debug or validate cf options are correctly passed

I have tried simplified version, by forcing the quality, but still no success:

addEventListener("fetch", event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  let url = new URL(request.url)

  let options = { cf: { image: {quality: 40} } }

  const imageURL = url.searchParams.get("image")
  if (!imageURL) return new Response('Missing "image" value', { status: 400 })
  const imageRequest = new Request(imageURL, {
    headers: request.headers
  })

  return await fetch(imageURL,  options);
}

  const imageURL = url.searchParams.get("image")
  if (!imageURL) return new Response('Missing "image" value', { status: 400 })
  const imageRequest = new Request(imageURL, {

  return await fetch(imageURL,  options);
}

Make sure the worker is running on a zone that has image transformations available
