how to use NutritionIntake with python fhirclient libary?

Question

Am using fhirclient libary "3.2.0" and I would need to make use of the FHIR NutritionIntake resource. My understanding is that it is not available as I could not find underl the "fhirclient.models.". Please, correct me if I am wrong.

My attempt to solve the above has been to implement "class NutritionIntake(DomainResource)". What I implemented so far is as per below. The issue that I am having is that when testing on the input containing "consumedItem" as per below, Get the following errors:

Please would you suggest any help on how to solve it?

Many Thanks, carlo
