i found answer that we need to start coordinate and close coordinates are the same value.

db.properties.find({
  location:{
    $geoWithin : {
      $geometry : {
        type:"Polygon",
        coordinates:[
            [
                [ 104.9212999921292 , 11.575955591122819 ] , // start loop
                [ 104.92129194550216 , 11.575198826419006 ] ,
                [ 104.92298978380859 , 11.575238241297862 ] ,
                [ 104.92291736416519 , 11.576023910057827 ] ,
                [ 104.9212999921292 , 11.575955591122819 ] // close loop
            ]   
        ]
       }
     } 
   }
})
