waitUntil not working in cloudflare pages preset

[retuerto]

Environment

Nuxt 3.12.4 with Nitro 2.9.7 with cloudflare pages preset through nuxthub

Reproduction

https://stackblitz.com/edit/github-ch89s7?file=routes%2Findex.ts,plugins%2Fbackground.ts

Describe the bug

I just found out that it works in development environment but it doesn't work as expected when deployed on cloudflare throught nuxthub. event.waitUntil gets blocked and the user waits for the response when it shouldn't happen like that. I tried this and it works:

const waitFor = (ms: number) =>
  new Promise((resolve) => setTimeout(resolve, ms))

async function backgroundTask(id: number) {
  await waitFor(5000)
  console.log(`Task ${id} is done!`)
}

export default defineEventHandler((event) => {
  const cfCtx = event.context.cloudflare.context
  const taskId = Math.round(Math.random() * 1000)
  event.context.taskId = taskId
  let now = new Date()
  console.log('Time before backgroundTask : ' + now.toLocaleTimeString())
  cfCtx.waitUntil(backgroundTask(taskId))
  now = new Date()
  return `Task ${taskId} is running in background... : ${now.toLocaleTimeString()}`
})

Additional context

No response
