Anyone with redux toolkit knowledge? The code below is causing my entire app to crash. Can anyone spot the problem in my asyncThunk because I can't...

export const getBarbers = createAsyncThunk(
  "/barbers/fetchBarbers",
  async () => {
    return fetch("/api/barbers").then((res) => res.json());
  }
);

Removing the async keyword remedies the app failure but I'm pretty sure I need that.
