未知尺寸“年龄”

如何解决未知尺寸“年龄”

我需要为某个数据集创建一个数据立方体模型。我在执行json模型时遇到了麻烦：

这是我的模型，可能会引起麻烦。

{
"dimensions": [
    {
     "name":"income","levels": [
            {
                "name":"region","label":"Region","attributes": ["region"]
            },{
                "name":"age","label":"Age","attributes": ["age"]
            },{
                "name":"shopper","label":"shopper","attributes": ["shopper"]
            }
        ]
    },{"name":"income","role": "amount"}
],"cubes": [
    {
        "name": "income","dimensions": ["income","age"],"measures": [{"name":"income","label":"Amount"}],"aggregates": [
                {
                    "name": "amount_sum","function": "sum","measure": "income"
                },{
                    "name": "record_count","function": "count"
                }
            ],"mappings": {
                      "item.income": "income","item.age": "age","item.shopper": "shopper","item.region": "region",},"info": {
            "min_age": "32","max_age": "55"
        }
    }
]}

我已经附上了数据集的屏幕截图，因此您可以直观地看到它的样子。

在执行以下单元格的状态期间引发的错误：

NoSuchDimensionError追溯（最近的呼叫 最后）
