This is parsing problem. Can you verify the response and see if it is a valid json. I would be appreciated if I can see the response. Thanks

[EnGassa]

The response here is a requests.models.Response object since httplib returns it. In case of non SOAP requests, in your code in utils.py on line 157 you call the response.json() to convert it to JSON. Since this code is used for all other calls too and seems to be working for those. I am guessing it is a problem isolated to the Salesforce update operation response.

In order to prove this hypothesis, I recently dived deep into the requests module and more specifically the json() method in it. It seems that the update response doesnt have encoding set unlike the others.

In [5]: sf.query('select firstname, id from contact limit 1')
GET: Sending request to https://na24.salesforce.com/services/data/v33.0/query/

<class 'requests.models.Response'>

    },

  } ]
}

Can you look at the network package and let me know the response. Or you can add a print in my sdk before line 157

[EnGassa]

The response is a 200: <Response [200]>

I am printing response.text too. This prints out the content of the response, and works for all the queries I make, except for Update.

[htarevern]

What is the content of the response.text in the case of update?

[EnGassa]

The type of response.text is unicode and the value is blank.

type: <type 'unicode'>, content:

[htarevern]
