Laravel whereIn with a where clause ErrorException in Grammar.php line 118:

Below is my laravel query:

$statusCondition = '[1]';

$users = DB::table('user_tracking')
                 ->join('user_detail', 'user_tracking.user_id', '=', 'user_detail.id')
                 ->select('user_tracking.*', 'user_detail.gender', 'user_detail.username', 'user_detail.auth_provider')
                 ->where('user_tracking.art_id','=','1')
                 ->where('user_tracking.visit_start_date','>',DB::raw('NOW()-INTERVAL 24 HOUR'))
                 ->whereIn('user_tracking.status',$statusCondition)
                 ->get();

When I'm using whereIn then given below error can anyone help to resolved such issue:
