Hi I'm trying to build a form that edit user profile whit a new avatar too but I have some problems to perform a request with avatar. The error in console is: PATCH http://127.0.0.1:8000/profile 500 (Internal Server Error) and the request bag is empty. Thnks

This is a page with form

import InputError from '@/Components/InputError';
import InputLabel from '@/Components/InputLabel';
import PrimaryButton from '@/Components/PrimaryButton';
import TextInput from '@/Components/TextInput';
import FileInput from '@/Components/FileInput';
import { Link, useForm, usePage } from '@inertiajs/inertia-react';
import { Transition } from '@headlessui/react';
import { useState } from 'react';

export default function UpdateProfileInformation({ mustVerifyEmail, status, className }) {
    const user = usePage().props.auth.user;

    const [avatar, setAvatar] = useState("https://ui-avatars.com/api/?name="+user.name+user.surname+"?rounded=true");

    const { data, setData, patch, errors, processing, recentlySuccessful } = useForm({
        name: user.name,
        email: user.email,
        avatar: ''
    });

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

        patch(route('profile.update'));
    };

    const changeAvatar = (e) => {
        setAvatar(URL.createObjectURL(e.target.files[0]));
        setData('avatar', e.target.files[0]);
    }

    return (

This is a input file component

import { forwardRef, useEffect, useRef } from 'react';

export default function FileInput( { type = 'file', name, id, className, required, handleChange }) {

    return (
        <div className="flex flex-col items-start">
            <input
                type={type}
                name={name}
                id={id}
                className={
                    `border-gray-300 focus:border-indigo-500 focus:ring-indigo-500 rounded-md shadow-sm ` +
                    className
                }
                required={required}
                onChange={(e) => handleChange(e)}
            />
        </div>
    )
