How can I change a payload array into a payload object in Node Red?

Question

In Node Red I have a message that has an array of three values as payload and I want to assign those values to three different properties of a payload object. How can I do that? Thank you

You can't directly move the array elements to msg.paload.X because you can't add arbitrary fields to the existing array objects.

So you'll need to move the array to a temp field first. You will also have to only ever move the first ([0]) element in the array because it will get shorter on every move as the first element is pop'd from the array.

And finally delete the temp filed.
