BQ（大查询）-修改JSON输出，以供BQ接受

Question

当前，使用API​​收集JSON文件。我设法提取了此输出，如下所示。

现在我在舞台上，我可以进行JSON提取，并且需要以BQ接受的方式进行。无需过多的操作（因为此输出可能会每天加载。

{
    "stats": [{
            "date": "2018-06-17T00:00:00.000Z",
            "scores": {
                "my-followers": 8113,
                "my-listed": 15,
                "my-favourites": 5289,
                "my-followings": 230,
                "my-statuses": 3107
            }
        }, {
            "date": "2018-06-18T00:00:00.000Z",
            "scores": {
                "my-statuses": 3107,
                "my-followings": 230,
                "my-lost-followings": 0,
                "my-new-followers": 0,
                "my-new-statuses": 0,
                "my-listed": 15,
                "my-lost-followers": 5,
                "my-followers": 8108,
                "my-favourites": 5288,
                "my-new-followings": 0
            }
        }
        .....
    ],
    "uid": "123456789"

当前我有此错误：

Errors:

即使“ my-new-followings”仅包含整数（最多5位数字），也是如此。
