i cant read the event messages from the evok client. All i get is always that error message

ERROR:websocket:error from callback <function on_message at 0xb67882b0>: string indices must be integers

import websocket
import json
import logging
#import time

logging.basicConfig()
# Replace this with your Neuron IP Address
url = "ws://127.0.0.1:8080/ws"

def on_message(ws, message):
        obj = json.loads(message)
        for single_obj in obj:
                dev = single_obj['dev']
                circuit = single_obj['circuit']
                value = single_obj['value']
                print "Value: " + str(value) + " Device: " + str(dev) + " Circuit: " + str(circuit)
        print message
def on_error(ws, error):
        print error

def on_close(ws):
        print "Connection closed"

def on_open(ws):
# Turn on filtering
        #ws.send('{"cmd":"filter", "devices":["ai","input",output]}')
        #ws.send(json.dumps({"cmd":"filter", "devices":["ai", "output"]}))
# Turn on DO 1.01
        ws.send(json.dumps({"cmd":"set", "dev":"relay", "circuit": "1", "value":0}))
        ws.send(json.dumps({"cmd":"set", "dev":"relay", "circuit": "2", "value":0}))
# Query for complete status
        ws.send(json.dumps({"cmd":"all"}))

#receiving messages
ws = websocket.WebSocketApp(url, on_open = on_open, on_message = on_message, on_error = on_error, on_close = on_close)
ws.run_forever()

The "cmd" "all" works fine at the first start
