Unexpected '00' Byte After mnauth_challenge in Version Message

[dinno-invis1ble]

When connecting to my node using P2P, I've noticed an additional '00' byte after the mnauth_challenge in the version message. I'm unsure if this byte should be considered padding and if it can be safely ignored. The parsing code appears to handle this situation, but I'd like clarification on whether this behavior is expected or if there's a recommended course of action.

I am using @dashpay/dashcore-p2p to connect to my node.

Parsing Code:

function(payload) {
  var parser = new BufferReader(payload);
  this.version = parser.readUInt32LE();
  this.services = parser.readUInt64LEBN();
  this.timestamp = new Date(parser.readUInt64LEBN().toNumber() * 1000);

  this.addrMe = {
    services: parser.readUInt64LEBN(),
    ip: utils.parseIP(parser),
    port: parser.readUInt16BE()
  };
  this.addrYou = {
    services: parser.readUInt64LEBN(),
    ip: utils.parseIP(parser),
    port: parser.readUInt16BE()
  };
  this.nonce = parser.read(8);
  this.subversion = parser.readVarLengthBuffer().toString();
  this.startHeight = parser.readUInt32LE();

  if(parser.finished()) {
    this.relay = true;
  } else {
    this.relay = !!parser.readUInt8();
  }
  if(parser.finished()) {
    this.mnAuthChallenge = null;
  } else if (this.version >= 70214) {
    this.mnAuthChallenge = parser.read(32).toString('hex');
  }
	if(parser.buf.length - parser.pos === 1) {
		const padding = parser.read(1).toString('hex')
		if(padding !== '00') {
			console.warn('Padding in version message is not 00')
		}
	}
  utils.checkFinished(parser);
}

Additionally, the provided parsing code includes a check for a single '00' byte at the end of the buffer. Is this expected behavior, and should it be handled in a specific way?

Any guidance or insights would be appreciated. Thank you!
