Angular Google Maps: unexpected output in mapClick

Hello, I just tried to output the data of $event using mapClick:

<agm-map [latitude]="lat" [longitude]="lng" (mapClick)="onChooseLocation($event)">
    <agm-marker [latitude]="lat" [longitude]="lng"></agm-marker>
</agm-map>
onChooseLocation(event) {
    console.log(event);
}

But instead of coords (that I expect) I just get a “c”, why?
