如何访问嵌套对象成员？访问result.final显示undefined求助

一直尝试访问嵌套对象的元素但未成功，查阅过Stack Exchange上的类似问题仍无法解决。尝试用console.log(result.final)访问最终元素，控制台显示undefined，恳请指教。

代码如下：

var data = '{"response":{"valid":true,"final":{"message":" MS02","tags":{"d1":"eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzUxMiJ9","d2":"JhbGciOiJIUzI1NiJ9eyJ0eXAiOiJKV1QiLC","d3":"dupb9WWT8ypQYWw6QblkM98xFBBRsamkkWLw","d5":"5EChV1KJ4ASeh9crZDR3fivnSz4wCDmCr2RSC0CUrkx","d6":"hiH1I1SI3NHCYZeva0_FrjgSgxOa_YW6ECxRdAY-w5w","ua":"y"},"ti":"","op":[]}}}';
var dataJson = JSON.parse(data);
var result = [];

result = Object.entries(dataJson).map(([key, value]) => ({ [key]: value }))
console.log(result)
console.log(result.final)

对dataJson使用typeof检测发现它是string类型，于是对dataJson再次执行JSON.parse，再次检测typeof显示为object，现在无需映射，直接用点运算符（result.final）即可访问嵌套值。
