Mongo php不能规范化查询:BadValue bad geo query'

我正在尝试使用php-mongo库建立一个查询来搜索mongo中的地理空间数据。

    {
    "_id" : ObjectId("536ecef59bdc8977f1e9c06f"),
    "location" : {
        "type" : "Point",

            ]
        ]
    },
    "bounds" : {
        "type" : "Polygon",
        "coordinates" : [
            [
                [

[

        "2dsphereIndexVersion" : 2
    }
]

    $mongo = new MongoClient("mongodb://someserver.com:27017");
    $marks = $mongo->selectDB('atlantic');
        $q = array('bounds' => array(
          '$geoWithin' => array(
              '$geometry' => array(
                  'type' => 'Polygon',
            'coordinates' => array(array(
                    array(40.125246,-74.327963),
                    array(40.125246,-74.325989),
                    array(40.123738,-74.325989),
                    array(40.123738,-74.327963),
                    array(40.125246,-74.327963)
            ))
              )
          )
       )
    );
$marks = new MongoCollection($marks,'Analyzer_Marks');
    $marks = $marks->find($q);
    //var_dump($marks);
    $results = array();
    if(!empty($marks)){
        foreach($marks as $mark) {
            $results[] = array(
                "location" => $mark['location'],
                "tile" => $mark['tile'],
                "status" => $mark['status']
            );
        }
    }

这是我得到的错误:
