onkeyup event expecting incorrect type

[timandella]

We have the following line of code in our angular project (where this.editor is the FroalaEditor component)

this.editor.events.on('keyup', (e: Event) => this.onKeyup.emit(new ComponentEvent('keyup', null, e)), false);

This was building fine in 4.1.0, but in 4.1.1 we now get a typescript error

Argument of type '(e: Event) => void' is not assignable to parameter of type '(event: string, param1?: any, param2?: any) => boolean | void'.

However, I added a console.log(e) to the function like so:

this.editor.events.on(
    'keyup',
    (e: string) => {
        console.log(e);
        this.onKeyup.emit(new ComponentEvent('keyup', null));
    },
    false,
);

This then reveals that although it may be expecting a string, it is actually still being passed in an event.

{altKey: false, bubbles: true, cancelable: true, changedTouches: undefined, ctrlKey: false, …}
