$event is of type object<stdClass> , but the function expects a object<League\Event\object> .
It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { }
$x = '123'; // string "123"
// Instead of
acceptsInteger($x);
// we recommend to use
acceptsInteger((integer) $x);
