The property calendar does not seem to exist. Did you mean calendar_id?

        //remove old timeslots
        $calendarMain->timeslots()->delete();
        foreach($events as $event){
            if(!($event = $this->parseEvent($event)))
                \Event::fire(new CaldavErrorEvent($this->calendar, 'problem during the parsing an event'));
            $calendarMain->timeslots()->create($event);

It seems like $event defined by $this->parseEvent($event) on line 107 can also be of type null; however, Illuminate\Database\Eloquent\Relations\HasOneOrMany::create() does only seem to accept array, maybe add an additional type check?
