I'm working with Reactjs and GraphQL integration. i got a problem when i'm doing mutation for new user.

Scenario: Creating user using Modals bootstrap. when successful create new user, it shows alert or information success.

Code: Here's my ModalCreate component code.

import React, { useState, useEffect } from 'react';
import { Button, Modal, Form } from "react-bootstrap";

const ModalCreate = (props) => {
    // state for check input component
    const [value, setValue] = useState({ 
                                    username: props.username || '', 
                                    email: props.email || '', 
                                    fullname: props.full_name || '',
                                    password: props.password || '', 
                                    phone: props.phone || '', 
                                    address: props.address || '', 
                                    groupid: props.group_id,
                                });
    
    const onChange = event => {
        setValue({
            ...value,
            [event.target.name]: event.target.value
        })
    }

    useEffect(() => {
        if (props.show) {
            document.body.classList.add("modal-open");
        }

        return () => {
            if (document.body.classList.contains("modal-open")) {
                document.body.classList.remove("modal-open");
            }
        };
  }, [props.show]);

  return (
    <Modal show={props.show}>
      <Modal.Header>
        <Modal.Title> <span>FORMULIR AKUN PENGGUNA</span> </Modal.Title>
      </Modal.Header>
      <Modal.Body>
        <Form onSubmit={e => { 
            e.preventDefault();
            props.action({
                variables: {
                    ...value
                }
            })
         }}>
            <Form.Group className="mb-3">
                <Form.Label>Role Akun</Form.Label>
                <Form.Select aria-label="pilih user role" value={value.groupid} onChange={onChange}>
                    <option value="superadmin">Super Admin</option>
                    <option value="admin">Admin</option>
                    <option value="admin_rj ">Admin RJ</option>

                <Form.Control name="username" value={value.username} onChange={onChange}/>
            </Form.Group>
            <Form.Group className="mb-3">

            <Form.Group className="mb-3">
                <Form.Label>Email</Form.Label>
                <Form.Control type="email" name="email" value={value.email} onChange={onChange}/>
            </Form.Group>
            <Form.Group className="mb-3">
                <Form.Label>Password</Form.Label>
                <Form.Control type="password" name="password" value={value.password} onChange={onChange}/>
            </Form.Group>
            <Form.Group className="mb-3">
                <Form.Label>Phone</Form.Label>
                <Form.Control type="text" name="phone" value={value.phone} onChange={onChange}/>
            </Form.Group>        
            <Button variant="secondary" type='submit'>
                Simpan
            </Button>
        </Form>
      </Modal.Body>
      <Modal.Footer>
        <Button variant="secondary" onClick={props.onClose}>
          Keluar
        </Button>
      </Modal.Footer>
    </Modal>
  );
};

export default ModalCreate;

            }
        </Container>
    )
}

export default PengaturanPengguna;

and here's my mutation:

const REGISTER_USER = gql`
    mutation($input: RegisterInput!) {
        register(input: $input) {
            username
            email
            full_name
            phone
            address
            group_id
        }
    }
`;

If you are getting validation error from apollo for required fields then check the form fields may be name attribute is missing and value is not storing inside your state.
