I have narrowed it down further.
The problem is with the ChannelListFromJson() function.
I added prints in that function and I can see that data going into function as parameter data is correct. I can see that it contains the channel info which I was expecting.

However, the json.Decoder call returns nil. .
With this I believe that the channelList declaration is not correct which is leading to incorrect decoding.type ChannelList []*Channel
