Facebook共享错误：“网站”类型的URL处的对象无效，因为未提供“string”类型的必需属性“og：title”

Question

出于某种原因，每次我尝试分享自定义故事时，只会在第一次尝试分享时出现以下错误：

Facebook分享错误：网址类型＆＃39;网站＆＃39;是无效的，因为必需的属性＆＃39; og：title＆＃39;类型＆＃39;字符串＆＃39;没有提供。

然而，当我检查我的元标记时，标记显然就在那里。

<meta property="og:title" content="sdfsdsafsd">

每当我第二次分享时，它都能完美运行。这是我的代码

$( document ).ready(function() {

  // You probably don't want to use globals, but this is just example code
  var fbAppId = '***';

  /*
   * This is boilerplate code that is used to initialize
   * the Facebook JS SDK.  You would normally set your
   * App ID in this code.
   */

  // Additional JS functions here
  window.fbAsyncInit = function() {
    FB.init({
      appId      : fbAppId, // App ID
      status     : true,    // check login status
      cookie     : true,    // enable cookies to allow the
                            // server to access the session
      xfbml      : true,     // parse page for xfbml or html5
                            // social plugins like login button below
      version        : 'v2.0',  // Specify an API version
    });

    // Put additional init code here
  };

  // Load the SDK Asynchronously
  (function(d, s, id){
     var js, fjs = d.getElementsByTagName(s)[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement(s); js.id = id;
     js.src = "//connect.facebook.net/en_US/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));

  /*
   * This function makes a call to the og.likes API.  The
   * object argument is the object you like.  Other types
   * of APIs may take other arguments. (i.e. the book.reads
   * API takes a book= argument.)
   *
   * Because it's a sample, it also sets the privacy
   * parameter so that it will create a story that only you
   * can see.  Remove the privacy parameter and the story
   * will be visible to whatever the default privacy was when

   *
   * Also note that you can view any story with the id, as
   * demonstrated with the code below.
