无法将JSON导入Parse后端

Question

所以我试图通过导入JSON文件在Parse后端创建一个类，但是我无法这样做。

我收到错误：

Row 1 is invalid: invalid field name : 15

我的JSON如下所示：

{
"results":[
{

"9": [ {"subject":"Operating Systems","room":"L21"} ],
"10": [ {"subject":"Microprocessors","room":"L21"} ],
"11": [ {"subject":"Chemistry","room":"L11"} ],
"12": [ {"subject":"Mathematics","room":"L16"} ],
"14": [ {"subject":"Chemistry Lab (G1)","room":""} ],
"15": [ {"subject":"Chemistry Lab (G1)","room":""} ],
"16": [ {"subject":"Chemistry Lab (G1)","room":""} ]
}

]

}

我在JSONlint上检查了它，我的JSON语法完全有效。

我错的任何帮助？
