Problem with .push() or for loop?!

What if you try looping the channels directly? Like

var channelArray = [];

for (let channel of doc.channels) {
  channelArray.push(channel.name);
};

I believe logic itself is fine here. Also, you should not get a Proxy object IMO (see this topic). Maybe that’s the reason, although I don’t see why it would be.

Could you also try just logging each channel? If it logs, see what’s the difference maybe between alpha and RGB :thinking:

for (let channel of doc.channels) {
  console.log(channel);
};
