How to test:
example contains evaluator spec:

 {
  "version": "1.0",
  "id": "DenialCodeContains",
  "description": "Checks if the response text includes the expected denial code.",
  "evaluatorTypeId": "uipath-contains",
  "evaluatorConfig": {
    "name": "Denial Code Contains",
    "targetOutputKey": "report",
    "negated": true,
    "ignoreCase": false,
    "defaultEvaluationCriteria": {
      "searchText": "mock report"
    }
  }
}

example eval set:

{
  "version": "1.0",
  "id": "ClaimDenialReview",
  "name": "Claim Denial Review",
  "evaluatorRefs": [
    "DenialCodeContains"
  ],
  "evaluations": [
    {
      "id": "denial-default",
      "name": "Respond with default denial code",
      "inputs": {
        "human_input": "Customer asks for the denial code on claim XFC-01."
      },
      "evaluationCriterias": {
        "DenialCodeContains": null
      }
    },
    {
      "id": "denial-override",
      "name": "Respond with override denial code",
      "inputs": {
        "human_input": "Customer asks if claim XFC-02 was denied and why."
      },
      "evaluationCriterias": {
        "DenialCodeContains": {
          "searchText": "mock sreport 1234 lala"
        }
      }
    },
    {
      "id": "denial-skip",
      "name": "Skip denial code check",
      "inputs": {
        "human_input": "Customer checks status of claim XFC-03 with no denial expected."
      },
      "evaluationCriterias": {}
    }
  ]
}
