Webex Contact Center Flow iterate through array

[nkravchenko]

Hello everyone,

I'm working on a Text-to-Speech (TTS) application where I need to iterate through JSON data retrieved from an API and vocalize each element. The JSON structure is as follows:

{
  "array": [
    {"elem": "a"},
    {"elem": "b"}
  ]
}

My goal is to loop through each element of the array and use the value for TTS. I set up a counter variable to dynamically access each element in the array using a JSON path expression. However, I'm encountering an issue when trying to use the counter variable dynamically in the path.

Here's path expression I'm using:

This approach doesn't seem to work, although hardcoding the index like $.array[0].elem works perfectly. Does anyone have insights into why dynamic indexing might not be working or how to correctly implement it in this context?

Thank you in advance for your help!

Try referring the variable in the braces $.array{{counter}}.elem
You can only refer variables in the braces
