We always recommend to pass responses to Alice with the dedicated JSON module, before the actual webhook response module. This way you make sure, that even more complex structures get transmitted to Alice properly. There are times when you won't get the results you want, especially when there are some calculations performed directly in the JSON of the response webhook.
This is why it's safer and better to create this response beforehand in the dedicated module:

And then, pass the result of this module to the Webhook response module:
