useFormik hook for user authentication

[MarkSinD]

Does anyone use useFormik hook? I need to validate username and password on the server. For validation I use the handleLogin(username, password) method. Here is my code:

const LoginForm = withFormik({
    mapPropsToValues: () => ({username: "", password: ""}),
    handleSubmit: (values, {props, setSubmitting}) => {
        const {handleLogin} = props;
        const {username, password} = values;
        handleLogin(username, password).then(() => { setSubmitting(false); });
  }
})(LoginView);

The fact is that if the validation is successful, it redirects me to the main page. This causes a memory leak error. Here is the text of the error:

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

    at Login (http://localhost:3000/static/js/bundle.js:13909:71)
    at div

Error at the place where then(() => { setSubmitting(false); }); is called. If you remove it and leave it like that, then everything works fine. But after all, the documentation says that you need to specify setSubmittingin the false state.

As far as I understand, the error occurs when it is impossible to assign a value. the component will be removed when you navigate to another page. How can this be fixed?
