    const authentication = getAuth();
    if (id === 2) {
      createUserWithEmailAndPassword(authentication, email, password).then(
        (response) => {
          sessionStorage.setItem(

                />
              }
            />

        </>
      </div>
    </Router>
  );
}

export default App;

Uncaught Error: useNavigate() may be used only in the context of a component. at invariant (index.tsx:19) at useNavigate (index.tsx:507) at App (App.js:23) at renderWithHooks (react-dom.development.js:14985) at mountIndeterminateComponent (react-dom.development.js:17811) at beginWork (react-dom.development.js:19049) at HTMLUnknownElement.callCallback (react-dom.development.js:3945) at Object.invokeGuardedCallbackDev (react-dom.development.js:3994) at invokeGuardedCallback (react-dom.development.js:4056)

Little Help is appriciated

Everything works fine when i remove useNavigate()

Answer 1

Your <Router> needs to be higher up the component tree than where you use useNavigate , but that's not the case currently. You're calling useNavigate in App, but the Router is inside App, not higher up the tree from App.

You'll probably want to split your components up. Something like this:

function App() {
  return (
    <Router>
      <SomeOtherComponent/>
    </Router>
  )
}

function SomeOtherComponent() {
  const [email, setEmail] = useState("");
  const [password, setPassword] = useState("");
  const [data,setData] = useState({});
  let navigate = useNavigate();

  // ... etc. Code is exactly the same as yours, just no Router in the return

  return (
    <div className="App">
      <>
        <Routes>
          // etc
        </Routes>
      </>
    </div>
  )
}
