Connect to a TCP Server with special packet order

// Assuming msg.payload is your JSON object

// Header
const HeaderBytes = Buffer.from("0xDEC0DA6E","hex")

// Length
const Str = JSON.stringify(msg.payload)
const SizeBytes = Buffer.allocUnsafe(4);
SizeBytes.writeInt32LE(Str.length);

// Data
const DataBytes = Buffer.from(Str, "utf-8");

msg.payload = Buffer.concat([HeaderBytes,SizeBytes,DataBytes])

return msg

I deleted the "0x" from the HeaderBytes so that the raw payload seems to be correct, but don't get any connection. [EDIT]: ...and - of course - changed the order of the Header Bytes because of the "lower byte first"...
Also the SizeBytes seems to be right - the first byte changes if I give one more character into the payload. But most probably there's some information missing for them to work.

I'll give a short feedback as soon as I managed to get the connection done!

Thanks!
Best,
