Facing this in macOS Catalina.
Works fine in macOS Mojave.

libc++abi.dylib: terminating with uncaught exception of type NSException

This issue looks similar, but the trace looks different.

Sending notification without an icon seems to work,
fails with the above exception when providing data url or image url

remote.require('node-mac-notifier') fixed this issue for me

Based on a report by a zulip-desktop user, this crash seems to follow the warning in #31. I wonder if that’s the root cause?

objc[87760]: Class NotificationCenterDelegate is implemented in both […]/node_modules/electron/dist/Electron.app/Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework (0x10974d0c0) and […]/node_modules/node-mac-notifier/build/Release/Notification.node (0x10a806a20). One of the two will be used. Which one is undefined.

Chromium and node-mac-notifier both define an @interface NotificationCenterDelegate. Can we rename the one in node-mac-notifier?
