Unset array replacing with null

[prafful-panwar]

            foreach ($event->volunteers as $key => $volunteer) {
                if ($volunteer['user_id'] == $userId) {
                    $event->where('volunteers.user_id', intval($userId))
                        ->unset("volunteers.$key");
                }
            }

Here is my DB structure

    "volunteers" : [
        null, 
        {
            "user_id" : NumberInt(1), 
            "name" : "Prafful  Panwar", 
            "skills" : [
                "Plumber"
            ], 
            "incentives" : {
                "tshirt_size" : "XXL"
            }, 
            "ready_to_contribute_min_amount" : "Yes", 
            "attendance_status" : false
        }
    ],

@prafful-panwar try to use $pull instead of $unset.
