Droping large sysex messages

[wylie39]

I am working on a project that transfers project data from a MIDI device, I am hitting a roadblock as it seems addListener("sysex") will drop large messages.
This is my test code:

WebMidi
  .enable({sysex: true})
  .then(() => {
    const myInput = WebMidi.getInputByName(deviceName);
    myInput.addListener("sysex", e => {
      console.log(e.rawData.length);
    })
  })
  .catch(err => alert(err));

It works fine for any small sysex messages, but if I try to receive a large one say 10,000 bytes it seems to get dropped, I can see that they are being received by MIDI monitor.
I have a hunch that it is only a problem on nodejs as when I use this test code in the browser it works as expected

navigator.requestMIDIAccess({sysex: true}).then(onMIDISuccess, onMIDIFailure);

function onMIDISuccess(midiAccess) {

    console.log("sysex enabled: ", midiAccess.sysexEnabled);

    for (var input of midiAccess.inputs.values()) {
        input.onmidimessage = message => console.log(message);
   }

}

function onMIDIFailure() {
    console.log('Could not access your MIDI devices.');
}

Any help would be appreciated

Just in case it is helpful:
Library version: 3.1.11
MacOS: 14.5 (23F79)
Nodejs: v16.15.1 tested on v18.19.1 as well

WEBMIDI.js has been created for the browser first. Support for Node.js was added later by piggy-backing on the jzz module. As of today, we have 3 pending issues that I suspect are caused by this module (all are Node-related). If your problem only occurs on Node, it seems very likely that it is caused by this external module. Unfortunately, the team behind jzz has not been very reactive. If this persists, we may have to move Node.js support to something else... I wish I could be more helpful.

That's sort of what I expected, I will poke around the jzz code and see if I can find the issue.
