Bug with getting a Coding answer from QuestionnaireResponse

[mkizesov]

Example:

from fhirpathpy import evaluate

evaluate(
    questionnaire_response,
    "QuestionnaireResponse.repeat(item).where(linkId='acc-have-claim-number').answer.value.Coding"
)

questionnaire_response = {
 "item": [
  {
   "item": [
    {
     "item": [
      {
       "answer": [
        {
         "value": {
          "Coding": {
           "code": "373066001",
           "system": "http://snomed.info/sct",
           "display": "Yes"
          }
         }
        }
       ],
       "linkId": "acc-have-claim-number"
      },
      {
       "answer": [
        {
         "value": {
          "string": "wfwefwf"
         }
        }
       ],
       "linkId": "acc-claim-number"
      }
     ],
     "linkId": "acc-claim-number-group"
    },
    {
     "linkId": "acc-claim-details-group"
    }
   ],
   "linkId": "patient-acc"
  }
 ]
}

KeyError: 'resourceType'

[mkizesov]

if we add resourceType to questionnaire_response, we'll get this error:

questionnaire_response['resourceType'] = 'QuestionnaireResponse'
evaluate(
    questionnaire_response,
    "QuestionnaireResponse.repeat(item).where(linkId='acc-have-claim-number').answer.value.Coding"
)
