Uncaught TypeError: Cannot read property 'toLowerCase' of null

[gossi]

I do get this error with v0.3.0, the mentioned line is:

ember-key-manager/addon/services/key-manager.js

Line 161 in dc0db28

const hasExecutionKeyMatch = eventExecutionKey.toLowerCase() === executionKey.toLowerCase();

[gossi]

I was looping over my user defined hotkeys:

macros.push(manager.addMacro({
	executionKey: node.get('hotkey'),
	keyEvent: 'keydown',
	callback: () => {
		// ...
	}
}));

Some nodes didn't had a hotkey and most likely had null registering, should be prevent by an error message, I guess?

👍 on a warning message if no 'executionKey' is specified.

@gossi do you want to take a stab at it and follow the same pattern that we did here? https://github.com/IcarusWorks/ember-key-manager/blob/master/addon/services/key-manager.js#L61
