Had the same issue in Chrome 57 on Mac OS, in a React JS project.

Error occurred when calling unbind in componentWillUnmount - notably though this only occurred after switching my project from React 15.3.1 to Inferno 1.6.2. It seems to be an issue with either my code or Inferno in my case - by the time unbind is being called the element has been removed from the DOM.

For me it’s specifically this line from unbind that is breaking:

# element-resize-event/blob/131c4d6fd01b6bd4a19d9698d37022b300fc2f51/index.js#L104
delete element.__resizeTrigger__.contentDocument.defaultView.__resizeTrigger__

I’m not sure if this is something that should be handled by the unbind function, but hopefully this information will be useful for any other devs encountering this problem.

No, seems like #28 does not help. Tried to use version from the master. But it still fails with error Cannot read property 'defaultView' of null in line element.__resizeTrigger__.contentDocument.defaultView.removeEventListener in unbind.
