创建一系列毁灭的一种嵌套的对象

Question 1

我需要建立一个系列的 id:'s范 entity: 变量内的嵌套 stakes 变量的对象 proposal. 当我使用这个代码解构的对象：

const {
   stakes: {
      entity: { id: SupportersId },
    },
 } = proposal
  console.log(SupportersId)

我得到的错误： TypeError: Cannot read property 'id' of undefined

这是一个`风险'可变的例子套内提议的对象，我应用的代码，是输出运行：

const {stakes} = proposal
console.log(stakes)

输出：

0: 
 amount: BigNumber 
    c: [100000] 
    e: 19 
    s: 1 
    __proto__: Object 
 createdAt: 1616006864000 
 entity: {id: "0x60893...734",
        __typename: "Supporter"} 
 id: "appAddress:0x8blahblah...entity:0x608same" 
 proposal: null 
 type: "Add"

时运行：

const {stakes: {entity}, }= proposal 
console.log(entity)

我得到：

4 Undefined
10 Undefined
10 Undefined
...

这是一个迭代 console.log(JSON.stringify(proposal))

希望有人可以帮我这个。我觉得我需要添加一个指数的变量的办法，你会当映通过一系列创建一个元素，但是，我还不肯定在什么这看起来就像无论是，可悲的。最后，我要通过这个清单作为一个孩子到另一个功能，将图通过它在另一种形式在我的应用程序以拉图像和资料数据从id创建一个"人卡"如果有帮助。任何帮助或建议，将不胜感激，谢谢！

Question 2

这里有一个例子，destructures正确。在这个例子中，我解构仅仅是第一个对象你的 proposal.stakes array(即： proposal.stakes[0]).

const proposal = {
    stakes: [{
        amount: 10n,
        c: [100000],
        e: 19,
        s: 1,
        createdAt: 1616006864000,
        entity: {
            id: "0x60893...734",
            __typename: "Supporter"
        },
        id: "appAddress:0x8blahblah...entity:0x608same",
        proposal: null,
        type: "Add",
    }]
};

const {
    stakes: [{
        entity: { id: SupportersId },
    }],
} = proposal;
console.log(SupportersId)

const {stakes: [{entity}], }= proposal;
console.log(entity);

提议的对象是东西，我正在通过后台。我想要创造的SupportersId变量地图的通过以后在应用程序在另一个组成部分。
@前锋，我更新我的职务，以对个事实，即你的 stakes 酒店是一系列的对象。
威克，你的男人！谢谢你们向我展示什么我失踪了。我很欣赏你的努力和知识！欢呼
@前锋,我好好的反馈意见。你可以点击勾接受这个答案，这是典型的方式，我们说"你是男人"在一起的溢出。 ;)
许多限制功能于一个新的用户喜欢的 @-用户和击，检查。但不得不说的，所以我做了:)
