Thank you in advance. I'm trying to slim down a JSON response from an external site in order to pass it through an IoT project. I can successfully make the external request, modify the response but I'm having some issues setting my new object as the body of my http response. I have tried setting the msg.payload to both a string (as regular json would be) and leaving it as a js object but still no luck

Am I supposed to go from function -> template ? to convert it to a string?
