I have a form in that form when I entered all details in Input form and when I click submit button the Form has to be Reset, I tried to Reset a form after clicking submit button. but it is showing this kind of error. TypeError: Cannot read property 'reset' of null

So please help me to resolve this error

This is my code App.js

import React, { useRef, useState } from "react";
import { Row, Col, Button, Card, Form, Input, Select } from "antd";
import axios from 'axios'
import 'antd/dist/antd.css';
import {
  SearchOutlined,
  StopOutlined,
  UserOutlined,
  LeftOutlined,
  DoubleRightOutlined,
} from "@ant-design/icons";
import './App.css';

const App = () => {
const { Option } = Select;

const [data, setData] = useState({});

const testData = async () => {
    try {
        const res = await axios.post('http://localhost:8000/api/user', data);
        console.log(res);
    } catch (error) {
        console.log(error);
    }

}

const handleChange = ({ target }) => {
  const { name, value } = target;
  const newData = Object.assign({}, data, { [name]: value });
  setData(newData);
}

const handleSubmit = (e) => {
  e.preventDefault();

  testData()
};
const myForm = useRef(null)
    const resetForm = () => {
        myForm.current.reset();

As said here you just have a syntax trouble.

Try this instead:

const myForm = useRef(null)
const resetForm = () => {
    myForm.reset();
}
