将嵌套的json分配给变量

Question

我有以下界面：

export interface IdataTypes {
dataType: {
  Categories: string[],
  isSelected: boolean,
}
}

和以下JSON

{
  "Sensitive Personal Data": {
    "isSelected": "false",
    "legalReference": "",
    "Categories": [
      "Health Data",
      "Genetic Data",
      "Biometric Data",
      "Trade Union Data",
      "Religious Data",
      "Political Opinion",
      "Philosophical Belief",
      "Racial or Ethic Origin",
      "Sex Life",
      "Sexual Orientation"
    ]
  },
"Personal Data with Higher Risk":{
  "isSelected":"false",
  "legalReference":"",
  "Categories":["location","Financial/Social Status","Data Related to Profiling",
    "video surveillance","data on adoption and custody"]
}


}

我想读取文件的“ dataTypeCategories” 并将其分配给Interface文件的变量。所以我要做以下

 for(let i=0; i<response["Personal Data with Higher Risk"].Categories.length;i++){
        this.dataTypeHighRisk["Personal Data with Higher Risk"][i].Categories.push
        (response["Personal Data with Higher Risk"].Categories[i]);
        this.dataTypeHighRisk["Personal Data with Higher Risk"][i].isSelected=false;
       ;
      }

我收到此错误：core.js：1542错误错误：未捕获（承诺）：ReferenceError：未定义类别

您能建议我如何做吗？我对javascript和angular都是陌生的。

更新，该数组定义为：dataTypeHighRisk：IdataTypes [] = []; 我不知道如何定义具有高风险的财产“个人数据/
