Key Server crashed/exited after receive one keyboard/mouse event.

[aztack]

MacOS 14.3 (23D56), M3 Chip. Node 20.2.0

Just install node-global-key-listener and touch index.js, paste demo code.
The node process exited after console.log out a keyboard/mouse event.

In the Activity Monitor, the Mac Key Server is disappeared after click mouse or tap any key.

But there no problem or crash when running the key server from command line.

Hi aztack,
can you try the latest version and see if you still have issues?

---

If you still have issues, can you try the following:

can you try pulling this repo and running the following commands:

npm install
npm run build
npm compile-mac
npm run test

and see if the tests run? I imagine the package just hasn't been built for mac in the published npm version.

Sorry for replying to your post so late. I tried above commands but got errors on the compile-mac step:

I'm using Xcode 15.4(15F31d) and MacOS Sonoma 14.5

update:
I added

import CoreGraphics

at the beginning of the main.swift and the compilation and test succeeded.
