      "valueExpression": {
        "name": "qr-search-phq9",
        "language": "application/x-fhir-query",
        "expression": "QuestionnaireResponse?subject={{%patient.id.replaceMatches('/_history/.*', '')}}&questionnaire=Questionnaire/54"
      }
    }

To Reproduce

searching by using variable is not affected by this ticket, however it might affect searching by using answerExpression.
this ticket does not affect engage migration to main, but is still interesting to check it's impact for answerExpression
