Javascript 使用lodash的带有数组的groupBy嵌套对象

我有一个JSON对象，如下所示

}]

我想要实现的是根据每个国家/地区数组中键的子字符串对每个国家/地区的数据进行分组

预期的JSON：

"Cyprus": [
"ABCDE": {
    "ABCDE0000010121": {
        "mou": 36.25,
        "CA": 3.0,
        "CCS": 2.0,
        "COC": 7.0
    },
    "ABCDE0000013643": {
        "mou": 27.299999237060547,
        "CA": 1.0,
        "CCS": 1.0,
        "COC": 6.0
    }
},
"EDCBA": {
    "EDCBA0000013662": {
        "mou": 80.59999752044678,
        "CA": 4.0,
        "CCS": 4.0,
        "COC": 14.0
    },
    "EDCBA0000010328": {
        "mou": 26.716670513153076,
        "CA": 4.0,
        "CCS": 4.0,
        "COC": 6.0
    }
}

] 我尝试使用loadash实现这一点，但没有成功

下面是我使用loadash编写的函数
