[BUG] Using defer, Expected a Response to be returned from queryRoute

[Mause]

I hope this method of reporting a bug is correct? This looks related to #4741 but not identical, and feels like a really basic case, so I'm not sure what's going wrong here

When running the submitted test, I get:

The following error is a bug in Remix; please open an issue! https://github.com/remix-run/remix/issues/new

This needs a default export to be treated as a UI route. Without it, it's being treated as a resource route which doesn't support defer

Suggested change

	export function Deferred() {
	export default function Deferred() {

[brophdawg11]

This looks like just a missing default export - with that added the deferred data is working correctly: https://stackblitz.com/edit/remix-run-remix-gkedbv?file=app%2Froutes%2F_index.tsx

Ah, thanks for the pointer, figured I'd made a silly mistake somewhere. Might be worth revisiting the error message though?
