Are you are setting websocket.binaryType to 'blob'?

Please share a minimal test case to reproduce the issue. I am unable to do it with the provided info. The following example works as expected.

import { WebSocket, WebSocketServer } from 'ws';
import { pack, unpack } from 'msgpackr';

const wss = new WebSocketServer({ port: 0 }, function () {
  const { port } = wss.address();
  const ws = new WebSocket(`ws://127.0.0.1:${port}`);

  ws.on('open', function () {
    ws.send(pack('Hello'));
  });

  ws.on('message', function (buf) {
    console.log(unpack(buf));
    ws.close();
  });
});

wss.on('connection', function (ws) {
  ws.on('message', function (buf) {
    ws.send(pack(unpack(buf)));
  });

  ws.on('close', function () {
    wss.close();
  });
});

@titanism are you are setting websocket.binaryType to 'blob'? Let's continue the discussion in #2239.

No, not at the moment. All we did was upgrade to latest version of ws and this issue came about.

Maybe it was already set. It was simply ignored before. I can't help without a test case.
