當使用者傳sticker時會出現以下error：

app.js

if (messageAttachments) {
    var json = JSON.parse(JSON.stringify(messageAttachments));
    var attachmentType = json[0]['type'];
    switch (attachmentType) {
      case 'audio':
        console.log('請稍後，我們已經收到語音檔案附件，馬上為你進行辨識');
        // response = {
        //   "text": `請稍後，我們已經收到語音檔案附件，馬上為你進行辨識`
        // }
        // callSendAPI(sender_psid, response);
        receivedAudioAttachment(sender_psid, json[0]['payload']['url']);
        break;
      case 'image':
          console.logs('sticker');
      default:
        console.logs('messenger type:'+attachmentType);
        response = {
          "text": `收到附件`
        }
        callSendAPI(sender_psid, response);
    }
  }

但是他卻顯示不出attachmentType，然後就一直卡住。
有什麼辦法可以讓他至少無視不要卡著嗎？
