Laravel：未捕获（承诺）错误：请求失败，状态码为422

Question

您好，目前我正面临这个问题。我能修好他。我不知道为什么会发生错误。

基本上，我试图将数据保存到DB中。我使用了Axios方法来获取和保存数据。在此之前，该功能运行良好，但突然导致了问题。拜托，任何人都可以帮助我。

Vue.js

<script>
    import Vue from 'vue'
    import axios from 'axios'
    import VueAxios from 'vue-axios' 

    import MarkdownIt from 'markdown-it'
    import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
    var msg_editor;
    Vue.use(VueAxios, axios);


    const md = new MarkdownIt({
        linkify: true
    })
// Vue.directive('select2', {
//         inserted(el) {
//             $(el).on('select2:select', () => {
//                 const event = new Event('change', { bubbles: true, cancelable: true });
//             el.dispatchEvent(event);
//         });
//         },
//     });
//  $('#condition').select2();
