Hi everybody.
Any body can help me?
I have trouble with upgrading existing react project.
I get this error; React Hook "useState" is called conditionally. React Hooks must be called in the exact same order in every component render react-hooks/rules-of-hooks.

Please help me any body.
That was working on react 16.13 but return that error on react 17
Help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I think you should handle playingSong state by useEffect hooks. like this:
const playSong = () => setPlayingSong(require(`.../sound/${title}.mp3`));
useEffect(() => {
if(playingSong) {
const audio = new Audio(playingSong);
type: "PLAY_SONG",
currentPlayingSong: audio
}, [playingSong]);

Afternoon lovely folk - i'm making my signup page a protected route, (so only registered users can make accounts for new users). I'm having trouble with persisting the state of the current user, when a new user is registered it replaces the details of the current logged in user.
signup = (userInfo) => {
return"/auth/signup", userInfo).then((response) => {
const { user, token } =;
localStorage.setItem("token", token);
localStorage.setItem("user", JSON.stringify(user));
if (this.state.user && Object.keys(this.state.user).length === 0) {
return response;
