error writing binary data to TCP socket.

[Stephen James]

Using electron I am trying to write out some bytes on a TCP socket. I am using Buffer.from to convert to buffer before calling write, but am still getting the above error. I have simplified it down to just creating an empty ArrayBuffer and calling Buffer.from

var abuff = new ArrayBuffer(8 + encodedBuffer.length);
console.log(Buffer.from(abuff));
socket.write(Buffer.from(abuff));

TypeError: Invalid data, chunk must be a string or buffer, not object at Socket.write (net.js:667:11)

The console.log shows the following:

Uint8Array(51) [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

and not Buffer?

Why would Buffer.from not create a Buffer?

This has been fixed since. I don't know when. I have Node 9.3 and it produces a Buffer.
