Question about onError

  onError((err) => {
    console.error(err);
  })

  onMount(() => {
    loadUserData(params.username)
      .then(setUser)
  })

  onError((err) => {
    console.error(err);
  })

  onMount(() => {
    loadUserData(params.username)
      .then(setUser)
  })

  onError((err) => {
    console.error(err);
  })

  onMount(() => {
    loadUserData(params.username)
      .then(setUser)
  })

  onError((err) => {
    console.error(err);
  })

  onMount(() => {
    loadUserData(params.username)
      .then(setUser)
  })

I've got a throw inside my loadUserData because I thought onError would catch it, so I guess I've misused onError.
