The Tanstack start + clerk quick start is broken.

I'm receiving this error after scaffolding then running the dev server:

TypeError: serverEntry.default.fetch is not a function

Looks like there was a breaking change with clerk outlined here: https://www.answeroverflow.com/m/1420141142724448306

createStartHandler,
defaultStreamHandler,
defineHandlerCallback,
} from "@tanstack/react-start/server";
import { createRouter } from "./router";
import { createClerkHandler } from "@clerk/tanstack-react-start/server";


const handlerFactory = createClerkHandler(
createStartHandler({ createRouter })
)
