The operation /model/exist always responds with a result:null and ecode:0 no matter if the model exists or not

When deployed as part of the ADOxxWeb API the /model/exist operation always returns the same result and ecode in the response, even though the inputs should lead to different results.

Example 1: not existing model

• modeltype: Business process diagram (BPMN 2.0)
• modelname: something

  "success": true,
  "startDate": "22.09.2025,12:56:15",

  "script": "CC \"Core\" UPDATE_MODEL_LIST \r\nCC \"Core\" GET_MODEL_ID modelname:\"something\" modeltype:\"Business process diagram (BPMN 2.0)\"\r\n\r\nSET adowsresponse:(ecode)",
  "duration": 77,
  "ecode": "0",
  "errorText": "No error",
  "result": null
}
