Need help with NetwrokSender

[mpg732]

I am trying to use the following Python script with Netwrok sender and getting an "NetworkSender failed" error.

import urllib
import json
f = urllib.urlopen('http://192.168.0.116:8080/tv/getTuned')
result = f.read()
data = json.loads(result)
duration = data["duration"]
eg.plugins.NetworkSender2.plugin.Send("Dir.Channel", [duration])

I have tested that NetworkSender is working correctly with this line,
eg.plugins.NetworkSender2.plugin.Send("Set.Volume", ["test"])
and the word "test" does show up on the other side.

Below is what I was hoping to see in the variable "Duration"
{
"callsign": "FXHD",
"date": "2008",
"duration": 7200,
"isOffAir": false,
"isPclocked": 3,
"isPpv": false,
"isRecording": false,
"isVod": false,
"major": 248,
"minor": 65535,
"offset": 2105,
"programId": "7495528",
"rating": "TV-G",
"startTime": 1387994400,
"stationId": 3900906,
"status": {
"code": 200,
"commandResult": 0,
"msg": "OK.",
"query": "/tv/getTuned"
},
"title": "Madagascar: Escape 2 Africa"
}
