Creating and testing error pipelines

I’m trying to create an error pipeline. A couple of questions… Is it supposed to be called regardless of whether there is an error or not? (It is. Am I doing something wrong? or is this expec...

    Yes but .map() function transforms every element from the Array, I only need to change the fields where there are numbers. Is there a way that I can use conditional logic inside of the .map() function?( if typeof value == ‘number’ then value * 10 else value

      Absolutely - the expression in the map function can use ternary logic just like you have in your example updating the object elements.

      Assuming an input array:

      { "myArray": [ "abc", 13, "def", 15 ] }

      This works as I believe you are requesting:
      $myArray.map(x => x instanceof Number ? x * 10 : x)

      { "updatedArray": [ "abc", 130, "def", 150 ] }

        You are right, in this case it works but in my case I have an array of objects which I finally managed to work with this: jsonPath($, "$nested[*]").map(x => x.mapValues((value, key) => !isNaN(value) ? value * 10 : value))

        Input:

        "nested": [{"m": "hey", "o": 10, "p": "hello", "q": 100}]

        Output:

        "nested": [{"m": "hey", "o": 100, "p": "hello", "q": 1000}]

        Thank you @koryknick for your guidance!
