Amazon SNS publish push notifications

I am using python for amazon SNS for publishing push notifications.

    data = { "GCM" : {"data":   {"message": "dummy"  }}}
    jsonData =  json.dumps(data)        

    self.client.publish( TargetArn=targetArn,
        Message= jsonData,
        MessageStructure='json')

Getting the below error.

Invalid parameter: JSON must contain an entry for 'default' or 'GCM'.

Tried sending it as string and various formats. But this is not working out. What's wrong with the publish?

The json strucutre needed by publish had to have \ escaped specifically. Below worked for me. It is important to have a default value and the value of GCM key should again be a json object. 

GCM_data = { 'data' : { 'message' : 'dummy'}}

data = { "default" : "test",
         "GCM": json.dumps(GCM_data)
        }
jsonData =  json.dumps(data)
