How to use Dynamic Channel from JSON URL

Hi,

I have JSON URL with Channels Ex: http://mytv.com/json.php

and i have coded in my config.brs like bellow

Function loadConfig() as Object
    channels = []
    request = CreateObject("roUrlTransfer")
    port = CreateObject("roMessagePort")
    request.SetMessagePort(port)
    request.SetUrl("http://mytv.com/json.php")
    jsonString = request.GetToString()

    json = ParseJSON(jsonString)
    for each channel in json.channels

        arrayElement = {
            Title: channel.Title
            streamFormat: channel.streamFormat
            Logo: channel.Logo
            Stream: channel.Stream
        }

        channels.push(arrayElement)
    end for

    return channels
End Function

But i am getting Following error in Console
