How to catch errors thrown from fetcher? What is the point of error?

[3pleFly]

Hello. I am a bit confused, if the fetcher throws an error, the error goes up to the useSWR hook, then it goes up from the where it was called until it reaches some error boundary or is uncaught.

What is the point of error returned from useSWR, if you can't reach it?

  const { data, error } = useSWR("123", () =>
    new Promise((resolve, reject) => { setTimeout(() => reject("Data"), 2500) }), {
      suspense: true, onError(err, key, config) {
        console.log(err,key)
// Can't catch but error goes through here, so it's only useful for logging?
        
      },
  })


  if (error) return <>Found error</> // <-------------- should never run, error was thrown 
 if(isLoading) return <>Loading</>

return <>{JSON.stringify(data)}</>
