Buffer not defined anymore in the payload format's JavaScript?

TTN Network and Services v2 Console
6

I’m not sure of the Buffer issue, or from where it originates (my lack of understanding/knowing the engine under the TTN hood and the languages), but clearly it was working in the past. I will look at “Is there any documentation on payload functions?” and will see if I can find an answer there.

Below is the first block of code from encoder.js from lora-serialization with just the unixtime variable. Is the second line Buffer(byteSize) causing the issue, or is it behind the scenes in TTN?

var intToBytes = function(i, byteSize) {
  var buf = new Buffer(byteSize);
  for (var x = 0; x < byteSize; x++) {
    buf[x] = i >> (x * 8);
  }
  return buf;
};

var unixtime = function(i) {
  if (isNaN(i) || i < 0) {
    throw new Error('Unix time must be positive');
  }
  return intToBytes(i, unixtime.BYTES);
};
unixtime.BYTES = 4;

Using lora-serialization alone would be great, but might decide to use it for decode with some of the other information you provide on the “best practices” link as a work around for the encoder. Is it possible to use one for decoding and another for encoding, as long as the node is programmed for that?
