I am trying to create a new person label using the api.
Following the guidelines at https://pipedrive.readme.io/docs/working-with-labels I must first read all the existing person labels, which returns ids, labels and colors. I must then write all this back, appending another item to the array (without an id), just the label and color.
I have done this in n8n to prove the concept - but only the existing labels are returned, the new one is ignored.
What am I missing please?
