React Data object 在控制台中可用，但在显示字段中未定义

Question

我完全糊涂了，这个组件一直渲染得很好。 我没有对组件本身进行任何更改，所以我不知道为什么它变得不开心。 它是一个简单的 mui Card 组件，使用 jsx 表达式按字段显示数据。 在返回中，控制台正在记录正确的数据 object，在 html 标记本身内，控制台显示对数据的访问，但所有特定字段都返回未定义。

            <div className = "card-body">{console.log("first div", client)}
                <div className = "row">{console.log("second div", client)}
                    <label>Birth Date: {new Date(client?.personalInfo?.dateOfBirth).toLocaleDateString()} {console.log("inside DOB tag", client)}</label>{console.log("within second div", client)}

控制台中引用的每个数组都有相同的单个 object 'client' 具有要显示的值。 数据来自上下文（我尝试更改以支持将其向下钻取但得到相同的结果），一旦 api 调用解决，就会显示内容。 我什至不得不添加条件链接以保持浏览器快乐，这样它就不会在第一次渲染时中断，尽管目前，取消条件链接也没有改变任何东西，也不会导致通常的错误。 我想可能是 label 标签丢了东西，所以我把它切换到 MUI 的排版，结果相同。

如果有人猜测缺少什么，请告诉我。
