I am constructing a POC. And I created a pass through proxy service for Google Plus. 
Without using any proxy service I get this is my output : 

```
 {
   "kind":"plus#person",
   "etag":"\"ExituU7aUpmkkfyD52VulzptThw/4J1clegrhxYC2fsJOu2XWCs1Ewg\"",

      "givenName":"Abhi"
   },
   "tagline":"hey guys ! ssup!! check out ma recnt videos... uploaded",
   "gender":"male",
   "aboutMe":"\u003cb\u003ehie, abhishek - ma full name \u003c/b\u003e\u003cdiv\u003e\u003cb\u003em a DANCER ,\u003c/b\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003ei luv ma dancing .\u003c/b\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003ei care ma dancing ,\u003c/b\u003e\u003c/div\u003e\u003cdiv\u003e\u003cb\u003ei jus hv a gr8 thng in me dats ma dancing.\u003c/b\u003e\u003c/div\u003e",
   "relationshipStatus":"single",
   "url":"https://plus.google.com/117488614303967062311",
   "image":{
      "url":"https://lh6.googleusercontent.com/-tF-ip0tUxD4/AAAAAAAAAAI/AAAAAAAAAAA/WKI3USUh_DA/photo.jpg?sz=50"
   },
   "urls":[
      {
         "value":"https://plus.google.com/117488614303967062311",
         "type":"profile"
      },
      {
         "value":"https://www.googleapis.com/plus/v1/people/117488614303967062311",
         "type":"json"
      }
   ],
   "organizations":[
      {
         "name":"our lady of nazareth high school",
         "title":"science",
         "type":"school"
      },
      {
         "name":"",
         "title":"BLUEBYTES",
         "type":"work"
      }
   ]
}

```

But when I try to do the same using a simple pass through service I get only : 

```
{
   "kind":"plus#person"
}

```

I read on the wso2esb site that they had a bug and the explanation given to resolve the bug was that json data received was not in the proper format. 
But now how do I resolve the problem. I mean is their any way I can manipulate the json data before the esb converts it into json data.
