I have an Electron app on macOS Sonoma (Intel arch). It has a native addon (app.node) using node-addon-api. Recently it crashed, with the stack trace (given below). What is the CF_IS_OBJC function inside the CFDataGetBytePtr function, and why did it crash there?
[NSEvent addGlobalMonitorForEventsMatchingMask:NSEventMaskKeyDown handler:^(NSEvent *event) {
// code using CFDataGetBytePtr function
}];
[NSEvent addLocalMonitorForEventsMatchingMask:NSEventMaskKeyDown handler:^NSEvent *_Nullable(NSEvent *event) {
// code using CFDataGetBytePtr function
return event;
}];
I have key events monitors attached using addGlobalMonitorForEventsMatchingMask and addLocalMonitorForEventsMatchingMask in my native code and they use the CFDataGetBytePtr function there. So I think the issue happened in the key event monitor handler when calling the CFDataGetBytePtr function because my native addon app.node is also present in the trace. Also from the third and fourth entry in the stack trace, it seems like it happened while the app was updating.
