500错误在Asp.Net MVC项目中的Ajax调用

Question

尽管服务器发送了响应（在调试器中看到），但从ajax发送的发布请求却出现500错误。响应设置为正确的URL，并由服务器执行。服务器返回结果，但在浏览器中显示错误状态500。

这是用于ASP.net MVC小型应用程序。

import Vue from 'vue';
import StarsWithLabel from '../components/StarsWithLabel';
import VueResource from 'vue-resource';
Vue.use(VueResource);

export default {

  components: {
    'star-with-label': StarsWithLabel,
  },

  data: function () {
    return {
      config: window['endpointBookmakersProperties'],
      comment_content: null,
      showReview: false,
      showReviewForm: true,
      comment: null,
      comment_id: null,
      error_msg: '',
      showErrorMsg: false,
      pendingRatings: [],
    };
  },

  methods: {
    onSubmit: function () {
      const request = this.config['comment_url'];
      const requestRating = this.config['rating_url'];
      this.$http.post(
        request,
        {
          author_name: this.config['author_name'],
          author_email: this.config['author_email'],
          user_id: this.config['post_author'],
          author: this.config['post_author'],
          post: this.config['post'],
          content: this.comment_content,
        },
        {
          emulateJSON: true,
          headers: { 'X-WP-Nonce': this.config['nonce'] }
        }
      ).then(response => {
        // disable form
        this.showReviewForm = false;
        // show review
        this.showReview = true;
        // get comment id
        this.comment_id = response.body.id;

        // get body data
        console.log(response.body);
        // update bookmaker rating

      }, response => {
        // error callback
        this.showErrorMsg = true;
        this.error_msg = response.body.message;
      });
      if (this.comment_id !== 'undefined') {
        this.$http.post(
          requestRating,
          {
            user_id: this.config['post_author'],
            bookmaker_id: this.config['post'],
            properties_id: 'bk_goodwill',
            value: 5,
            comment_id: this.comment_id,
          },
          {
            emulateJSON: true,
            headers: { 'X-WP-Nonce': this.config['nonce'] }
          }
        ).then(response => {
          // get status
          console.log(response.status);

          // get status text
          console.log(response.statusText);

          // get body data
          console.log(response.body);

          // update bookmaker rating

        }, response => {
          // error callback
          this.showErrorMsg = true;
          this.error_msg = response.body.message;
        });
      }
    },
    onClickChild (value) {
      console.log(value);
    }
  },

};
</script>

<template>
    <div>

        <div v-if="showReview" class="current_user_review">
            <h3>Ваш отзыв:</h3>
            <div class="user-review">{{this.comment_content}}</div>
        </div>

        <div v-if="showErrorMsg">
            <h3>Произошла ошибка:</h3>
            <div class="error-review">{{this.error_msg}}</div>
        </div>

        <div v-if="showReviewForm">
            <h3>Оставить отзыв</h3>
            <div>
                <span @sent-rating-in-parent="onClickChild"></span>
            </div>
            <div class="add_reviews_form">
                <div class="bookmaker-ratings-items">
                    <div v-for="(value, property) in config['bookmaker_properties']" :key="property.id" class="rating-items" :id="property">
                        <star-with-label :label="value" :property="property"></star-with-label>
                    </div>
                </div>

                <form v-on:submit.prevent="onSubmit" class="new_review_form">
                  <textarea rows="8" cols="20" v-model="comment_content"></textarea>
                  <input type="submit" value="Отправить" class="btn btn-default btn-lg2 btn--is-s1">
                </form>
            </div>
        </div>

    </div>
</template>```

这在C＃中：

    $(window).on("load", function () {
    console.log("LOADING");
    $.post("/Play/Word", {}, function (data) {
    console.log(data['content']);
});
