ckfinder показывает сообщение «невозможно загрузить файл», но все еще сохраняет в папке

Question

Я использую ckfinder на ckeditor для загрузки изображения. Изображение правильно сохраняется через контроллер laravel, но я получаю всплывающее сообщение «Не удается загрузить файл». Изображение временно отображается в форме и затем скрывается после нажатия кнопки «ОК» в сообщении. Я часами просматривал документацию и безуспешно пробовал разные варианты конфигурации. Пожалуйста, помогите мне определить ошибку.
Это код моей формы:

import React, { useState, useEffect } from 'react';
import ReactDOM from 'react-dom';
import CKEditor from '@ckeditor/ckeditor5-react';
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';

export default function ArticuloForm(props) {       
    const handleShow = () => setShow(true);
                    const onSubmit = data => {
                        let formData = new FormData();
                        let details = JSON.stringify(data);
                        formData.append('data', details);
                    if (props.data.imagen) formData.append('image', 
                        props.data.imagen, 
                        props.data.imagen.name);
                        const result = axios
                            .post('http://www.localhost/api/saveArticulo', 
                            formData)

                        return setMounted(false);
                    };

                    return (
                        <div className="container mt-5">

                                    data={content || ''}
                                    onInit={editor => {
                                        console.log('Editor is ready to use!', editor);
                                    }}
                                    onChange={(event, editor) => {
                                        const data = editor.getData();
                                        setContent(data);
                                        setDirty(true);
                                    }}
                                    config={{
                                        ckfinder: {
                                            uploadUrl: 'http://www.localhost/api/ckUpload',
                                        },
                                    }}

                            </div>
                        </div>
                    );
                }


        This is the ckfinder.php configuration file where I have changed settings without success.
