I'm trying to run this web-extension example: https://github.com/mdn/webextensions-examples/tree/main/native-messaging on Linux (latest firefox) and macOs (latest firefox dev) and on calling browser.runtime.connectNative('ping_pong'); I get a disconnect event with a null error object.

Came here to raise the same issue, this native messaging ping pong hello world demo is broken on Linux for me 👎

Broken on macOS Sonoma 14.5 and Firefox 128.0 as well.
After the browser.runtime.connectNative(...) call the port is immediately disconnected without an error.
The app script is not even started once.
