Hi Peter,
Thanks for raising your concern.
You need to create also the instances of the resources and operation needed in
LabelService.MutateLabels. You will need to create
TextLabel instance first and supply values to the
background_color and
description field. Then, wrap the
TextLabel, together with the other required fields mentioned on the
label resource, in a
LabelOperation (create), and lastly send it to
LabelService.MutateLabels.
Let me know if you have further questions.
Regards,
