Task Explanation:
- Iterate through the children in Step Function 1
- Forward each JSON object to Step Function 2
- Upon completion of Step Function 2, a response is obtained from an external API
- Utilize this API response within Step Function 1
Visual Representation:

Code Example:
this.iterateChildren = new Iterate(this, "Iterate Children", {
itemsPath: "$.data.children",
maxConcurrency: 1,
resultPath: "$.children",
});
this.iterateChildren.iterator(new ForwardToExternalAPI(this, 'Send Data to Step Function 2', {
stateMachine: stepFunction.Two,
integrationPattern: IntegrationPattern.REQUEST_RESPONSE,
resultPath: "$.stepFunctionTwoResponse"
});
Currently, the resultPath only displays details about the step function execution. How can I retrieve data back from Step Function 2?
