I am trying to determine whether I have made a mistake in my request somewhere or if this is truly an error on the server side. Thanks for reading.

Hello Jonathan,

Apologies for the late response. The issue is with valueQuantity.code field. please use the below valueQuantity.

"valueQuantity": {
    "value": 215,
    "unit": "mg/dl",
    "system": "http://unitsofmeasure.org",

    "code": "mg/dL"
  }

Thank You,
