react react-hook-form useeffect JavaScript

I just started working with I've spent hours debugging this and I'm sure I'm missing something obvious here, but I'm using React Hook Form with a nested `useEffect` to reset form values under certain conditions, but I'm facing unexpected behavior where the values are not resetting as intended..... The form is wrapped with `FormProvider`, and I've set up my `useEffect` to depend on a state variable that changes based on user input. Here’s a simplified version of my implementation: ```javascript import React, { useEffect } from 'react'; import { useForm, FormProvider } from 'react-hook-form'; const MyForm = () => { const methods = useForm({ defaultValues: { name: '', age: '', }, }); const { watch, reset } = methods; const formData = watch(); const [userInput, setUserInput] = React.useState(''); useEffect(() => { if (userInput === 'reset') { reset({ name: '', age: '', }); } }, [userInput, reset]); return ( <FormProvider {...methods}> <form> <input type="text" {...methods.register('name')} placeholder="Name" /> <input type="number" {...methods.register('age')} placeholder="Age" /> <button type="button" onClick={() => setUserInput('reset')}>Reset</button> </form> </FormProvider> ); }; ``` The goal is that when I click the 'Reset' button, it should reset the form fields to their default values. However, I noticed that the reset function is not being called correctly, and the fields are not being cleared as expected. Sometimes, it appears that the old values linger or do not reset at all unless I trigger a re-render elsewhere in the component. I have tried moving the `reset` function outside of the `useEffect`, but that led to other issues as well. I’m using React Hook Form version 7.0.0. Has anyone faced similar issues? Is there a specific way I need to structure my `useEffect` with the `reset` function so it works consistently? This is part of a larger application I'm building. Am I missing something obvious? I've been using Javascript for about a year now.
