I receive this error while trying to implement JWT Authentication, Error: Maximum update depth exceeded

Question

I am receiving this error

Error: Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.

I am trying to use JWT along with reduxtoolkit and react but when i entered the correct username and password i received this error.

function Login() {
    const history=useHistory()
    const dispatch=useDispatch()
    const loginToken=useSelector(loginTokenSelector)
    const {register,handleSubmit,errors}=useForm()
    const onSubmit=data=>{
        dispatch(createLoginToken({
            username:data.username,
            password:data.password
        }))
        const isAuthenticated=localStorage.getItem('accessToken')
            ?true:false
        if(isAuthenticated) history.push('/')      
    }
    return (
        <Container>
            <form onSubmit={handleSubmit(onSubmit)}>

Answer 1

You are invoking the submit function on render. Wrap it in a new function:

<form onSubmit={() => handleSubmit(onSubmit)}>
