I imported `<Routing/>`

Question

I imported <Routing/> to Main App, then the error TypeError: Object(...) is not a function occurred.

My app is working without the component, but I need fix this error. Please help me.

const Routing = () => {
  const history = useHistory();
  const { state, dispatch } = useContext(UserContext);

  useEffect(() => {
    const user = JSON.parse(localStorage.getItem("user"));

    if (user) {
      dispatch({ type: "USER", payload: user });
    } else {
      if (!history.location.pathname.startsWith("/reset"))
        history.push("/signin");
    }
  }, []);

  return ();
};


function App() {
  return (
    <>
           ***<Routing />***
    </>
  );
}

Your full code with corrections:

const Routing = () => {
  const history = useHistory();
  const { state, dispatch } = useContext(UserContext);
  useEffect(() => {
    const user = JSON.parse(localStorage.getItem("user"));
    if (user) {
      dispatch({ type: "USER", payload: user });
    } else {
      if (!history.location.pathname.startsWith("/reset"))
        history.push("/signin");
    }
  }, []);
  return <></>;
};

function App() {
  return (
    <>
      <Routing />
    </>
  );
}

export default App;
