react html forms validation JavaScript

I need help solving I'm reviewing some code and I'm working with an scenario where my HTML `<form>` isn't submitting as expected in my React 17 application. I have a simple form with a couple of input fields and a submit button. When I try to submit, I see the validation errors being triggered correctly, but I can’t figure out why the form isn’t submitting after correcting the input values. Here’s the code snippet for my form: ```jsx import React, { useState } from 'react'; const MyForm = () => { const [name, setName] = useState(''); const [email, setEmail] = useState(''); const [errors, setErrors] = useState({}); const validate = () => { const newErrors = {}; if (!name) newErrors.name = 'Name is required'; if (!email.includes('@')) newErrors.email = 'Email is invalid'; setErrors(newErrors); return Object.keys(newErrors).length === 0; }; const handleSubmit = (e) => { e.preventDefault(); if (validate()) { // Simulate an API call console.log('Form submitted:', { name, email }); } }; return ( <form onSubmit={handleSubmit}> <div> <label>Name:</label> <input type="text" value={name} onChange={(e) => setName(e.target.value)} /> {errors.name && <span>{errors.name}</span>} </div> <div> <label>Email:</label> <input type="text" value={email} onChange={(e) => setEmail(e.target.value)} /> {errors.email && <span>{errors.email}</span>} </div> <button type="submit">Submit</button> </form> ); }; export default MyForm; ``` When I attempt to submit the form without filling in the fields, the errors display correctly. However, even after correcting the inputs, the form doesn't appear to get submitted – the console log is never triggered. I checked the browser console and noticed: `Uncaught TypeError: want to read properties of undefined (reading 'name')` This behavior seems to point to an scenario in my validation logic, yet I can’t pinpoint where it’s failing. I’ve tried moving the validation logic around and even simplifying it, but the question continues. Any insights on what could be causing the form submission to unexpected result or how to better handle this validation process? I’m using React 17 and trying to adhere to best practices for handling forms in React. This is for a desktop app running on macOS. What am I doing wrong? Thanks for taking the time to read this!
