如何解决请求的实体没有被发现？

我试图通过谷歌位置API的示例请求

  "considerIp": "false","wifiAccesspoints": [
    {
      "macAddress": "84:d4:7e:09:a5:f1","signalStrength": -43,"signalToNoiseRatio": 0
    },{
      "macAddress": "44:48:c1:a6:f3:d0","signalStrength": -55,"signalToNoiseRatio": 0
    }
  ]
}

和我正在此错误

"error": {
        "code": 404,"message": "Requested entity was not found.","errors": [
            {
                "message": "Requested entity was not found.","domain": "global","reason": "notFound"
            }
        ],"status": "NOT_FOUND"
