I want to modify response using Scripting tool. My response is complicated json with nested objects and arrays that looks like that
payload: {
...........
result{
........
value[
.......
"something_i_want_to_change":"123",
.......
]
.........
}
}

How can I replace "123" value to "321"?

Hey @Floperoid, since the body is an Object (Dictionary), so you can access the value as usual. For example:

var body = response.body;

// Change it here
body.payload.result.value[0]. something_i_want_to_change = 123;

// Set it again
response.body = body

If it's too difficult to access a child node from a large JSON, you can export your Response first (Right-click on the Flow -> Export Response Body)

Then set a response.bodyFilePath as a file path.

function onResponse(context, url, request, response) {
 
  response.headers["Content-Type"] = "image/png";
  response.bodyFilePath = "~/Desktop/image.png";
 
  // Done
  return response;
}

Then, you can easily edit the JSON file with your favorited editor (VS Code or Sublime) 👍

Thank you a lot! Turns out It was my inadvertence
