如何在颠簸转换中在数组中添加索引

Question

我正在尝试修改输入内容，并使用'-indexNum'为每个对象添加一个ID，但这似乎不起作用。这里我发布了代码。

我的输入

 {
   "employees": [{
        "f_name": "tom",
        "l_name": "smith"
    },
    {
        "f_name": "don",
        "l_name": "jones"
    }
 ]
}

预期o / p：

{
"employees": [{
    "firstName": "tom",
    "lastName": "smith",
    "test": "emp-"
}, {
    "firstName": "don",
    "lastName": "jones",
    "test": "emp-"
}]
}

我的规格

[{
    "operation": "shift",
    "spec": {
        "employees": {
            "*": {
                "f_name": "employees[&1].firstName",
                "l_name": "employees[&1].lastName"
            }
        }
    }
},
{
    "operation": "modify-overwrite-beta",
    "spec": {
        "employees": {
            "*": {
                "test": "=concat('emp-',)"
            }
        }
    }
}]

我正在尝试修改输入内容，并使用'-indexNum'为每个对象添加一个ID。有人可以建议我帮忙。
