Adapter not supporting binary data

[tmotagam]

Hi,
I am trying to send binary data UInt8Array the data is going from client to server properly but when the server broadcast the received data the other server in the cluster is not receiving the data it receives this.

{ placeholder: true, num: 0 }

when I see the mongodb collection also shows what I receives on the receiving client.
Also the client on the receiving end disconnects once this malformed data starts to come in

socket.io server version: 4.5.4
socket.io client version: 4.5.4
nodejs: 18.0
os: windows
mongodb: 5

Hi! I could indeed reproduce with the latest mongodb version, I'm digging into this.

OK, so I think I have found the culprit, this should be fixed by socketio/socket.io-parser@ae8dd88, included in socket.io-parser@4.2.2.

I've also added a test here: ea20cce

Thanks a lot for the clear report 👍

Please reopen if needed!
