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

This issue looks similar, but the trace looks different.

[ghost]

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?
