How to give values with array of objects as input to a step function input?
问题
我有一个阶梯函数输出，格式如下：
[{
"status" : "VALIDATION_FAILED",
"memberData":{
"metaData" : {
"fileId" : 101,
"FileName" : "abc.txt"
}
}
}]
现在我只想将 metaData 作为输入传递给步骤函数的下一步。
通常我们通过使用 inputPath: $.status 等方式访问数据。但我怀疑，由于存在 [ ]，它给我一个错误：
' 无效路径 '$.status' ：在路径 $ 中未找到属性 ['status']。
由于同样的原因，我无法访问任何变量。请问有人能指导我如何解决这个问题吗？
我找到了一些解决方案，但没有找到我需要的。

I have a step function output in the below format:
[{
"status" : "VALIDATION_FAILED",
"memberData":{
"metaData" : {
"fileId" : 101,
"FileName" : "abc.txt"
}
}
}]
Now I only want to give metaData as input to the next step in my step function.
Usually we access the data by using inputPath: $.status and so on. But I suspect, due to the presence of [ ], it's giving me an error of
' Invalid path '$.status' : Property ['status'] not found in path $.
I m unable to access any variable inside for the same reason. Can anyone please guide on how do I address this?
I came across some solutions but didn't get what I m looking for

A filter expression similar to the following can be used given the output above:
$[0].memberData.metaData
