arrays - Node : How to store JSON Array in google datastore

Question

我尝试使用nodeJS在Google数据存储中存储以下对象，但它返回400“错误请求”错误

{
			   "_id":{
				      "$oid":"567e9e80067de880273095e0"
				   },
				   "name":"Windows 10",
				   "desc":"This is a Test",
				   "isSelfPaced":true,
				   "credit":[
				      {
				         "_id":"56640d4926b67c201b861cde",
				         "username":"Akash",
				         "displayName":"Gupta",
				         "email":"yesitsakash@gmail.com",
				         "role":"Author"
				      }
				   ],
				    				      
				   "video":{
				      "type":0,
				      "videoKey":"KHATEmotionalFulls_lowb84c0084-836c-008c-a850-328687e23d02.mp4",
				      
				   },

				   "structure":4,
				   "category":"test2",
				   "subCategory":"dfdfdf",

				            {

				                  "videoKey":"VID-20150920-WA0017ee56049d-2b08-aeb5-9b9c-b5188b1f7324.mp4",
				                  
				               },
				               "note":"<ul><li><b>This is a test<\/b><\/li><\/ul>",
				               "isSelfPaced":true
				            },
				            {
				               "id":"da4f53a3-7ea2-4fa8-9d48-4d7199a3450c",

				               "subtype":3,
				               "questions":[
				                  {
				                     "question":"New Question",
				                     "options":[
				                        {
				                           "text":"option 1",
				                           "correct":true
				                        }
				                     ]
				                  }
				               ],
				               "isSelfPaced":true
				            }
				         ],
				         "time":3,
				         "isSelfPaced":true,
				         "desc":"This is a test"
				      }
				   ],
				   "createdBy":{
				      "displayName":"Gupta",
				      "id":"56640d4926b67c201b861cde"
				   },
				   "createdAt":{
				      "$date":"2016-01-10T17:51:15.635Z"
				   },
				   "startDate":"1970-01-01T00:00:00.000Z",
				   "endDate":"1970-01-01T00:00:00.000Z",
				   "isPublish":true
				};
	  datastore.insert('test2','test2',data,function(err,key){
		  if(err){
			  res.status(500).end();
		  }
		  else{
			  res.send(key);
		  }
	  });
	});

NodeJS 代码:

var keyObject = dataset.key({
		  namespace: namespace,
		  path: [collectionName,utility.getGUID()]
		});
	dataset.save({key:keyObject,data:data,method:'insert'},function(err) {
		if(err){
			callback(err,null);
		}
		else{
			callback(null,keyObject.path[1]);
		}
		
	});

更简单的场景正在运行，但如何使用nodejs将json数组存储在谷歌数据存储中

问题是 JSON 负载格式错误。
