title: Adapter Mobile First doesn't get the response
body: <p>I have problem when my cordova apps try to call the procedure in adapter, the adapter doesn't return the response.
  The response of adapter is just like this :</p>
  
  <pre><code>errorMsg: "OK"
  invocationContext: null
  responseHeaders:
  cache-control: "no-cache"
  connection: "close"
  content-type: "text/html; charset=UTF-8"
  expires: "0"
  pragma: "no-cache"
  __proto__: Object
  responseText: "&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;&lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;&lt;head&gt;&lt;META HTTP-EQUIV="CONTENT-TYPE" CONTENT="TEXT/HTML; CHARSET=utf-8"/&gt;&lt;title&gt;Error&lt;/title&gt;&lt;/head&gt;&lt;body&gt;&lt;H2&gt;Error&lt;/H2&gt;&lt;table summary="Error" border="0" bgcolor="#FEEE7A" cellpadding="0" cellspacing="0" width="400"&gt;&lt;tr&gt;&lt;td&gt;&lt;table summary="Error" border="0" cellpadding="3" cellspacing="1"&gt;&lt;tr valign="top" bgcolor="#FBFFDF" align="left"&gt;&lt;td&gt;&lt;STRONG&gt;Error&lt;/STRONG&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr valign="top" bgcolor="#FFFFFF"&gt;&lt;td&gt;This page can't be displayed. Contact support for additional information.&lt;br/&gt;The incident ID is: N/A.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/body&gt;&lt;/html&gt;"
  status: 200

  <p>I have no idea whats the problem is. Please Help to solve this.</p>
  
  <p>Update:
  This is payload that I send into adapter (REST)</p>
  
  <pre><code>{
    "id": "xxx",
    "userID": "ANDxxx",
    "firstName": "ANDY",
    "lastName": "JOHNSON",
    .............
  }
  </code></pre>
  
  <p>Notes :
  - I use mobile first 8.0.0.00-20180504-092633 version
  - I think it's intermittent. Because just some data in payload that I sent into adapter that return no response</p>
