Problems with Observation Component

[Benusheart]

Good morning,
I am working with FHIR and Python for the first time. As a test, I would like to create an observation that consists of several individual values. It was therefore obvious for me to work with component. Unfortunately, I cannot pass component, no matter what I do:

from fhir.resources.observation import Observation
comp={"component": [
      {
        "code": {
          "coding": [
            {
              "system": "http://loinc.org",
              "code": "39125-0",
              "display": "Width of Wound"
            },
            {
              "system": "http://snomed.info/sct",
              "code": "401239006",
              "display": "Width of wound"
            }
          ]
        },
        "valueQuantity": {
          "value": 4,
          "unit": "cm",
          "system": "http://unitsofmeasure.org"
        }
      },
      {
        "code": {
          "coding": [
            {
              "system": "http://loinc.org",
              "code": "39126-8",
              "display": "Length of Wound"
            },
            {
              "system": "http://snomed.info/sct",
              "code": "401238003",
              "display": "Length of wound"
            }
          ]
        },
        "valueQuantity": {
          "value": 3,
          "unit": "cm",
          "system": "http://unitsofmeasure.org"
        }
      }
    ]}
newObservation=Observation.construct()
newObservation.component=comp["component"]

i have the component from https://sciphy-stats.com/post/hl7-fhir-fundamentale-create-an-observation-resource/
I know there is an ObservationComponent but that didnt work, too.
What am I doing wrong or what do I have to change? Do you have an example? I would be incredibly grateful for an answer!

Update: Validation with similar component setup would work. Observation: https://ig.fhir.de/basisprofile-de/0.2.30/Blutdruck.html

    ]
}

obsi=construct_fhir_element("Observation",k)
print(obsi.json())
obsi2=obs.Observation.construct()
print(obsi2)
obsi2.component=k["component"]

but the assignment does not work :

I would suggest you, please read here #56
#57

Let me know if you have any confusion.

FYI: Observation.status is a mandatory field.

Thank you very much, that was my mistake!
