-This is because you subclassed `Trait` but forgot to pass through the arguments
-from your subclass constructor to the superclass constructor. Always default
-to writing your Trait definition like:
-
-```
-class MyTrait extends Trait {
-
-  initialize() {
-    // ...
-  }
-
-}
-```
-
-All trait initialization should be done in `initialize`.
-
-If you need really need to access arguments in your subclass constructor, opt
-to pass along `arguments` instead, such as:
-
-```
-class MyTrait extends Trait {
-
-  constructor(entity, params, state) {
-    super(...arguments);
-    // ...
-  }
-
-}
