karate : How to set the Json value if object name contains period in an array

Question

Here is my JSON request example code and as u can see #(Paramtervale) as to be replaced by MyValue

Below is the example of the request json and code:
            * request 
    """
            {
          "query": {
            "bool": {
              "must": [
                {
                  "match_data": {
                    "Event.Data.message": "#(Paramtervale)"
                  }
                },
                {
                  "match_data": {
                    "Event.Name": "#(Paramtervale2)"
                  }
                }
              ],
              "filter": {
                "range": {
                  "@timestamp": {
                    "gte": "now-1m"
                  }
                }
              }
            }
          }
        }
            """
* set request.Event.Data.message = myvalue
* set request.{Event.Data.message} = myvalue
* set request.(Event.Data.message) = myvalue

None of the above is working, can anyone please help

Answer 1

Here are 2 different ways, note that for updating a JSON, set is not needed any more. When special characters are in key names, use the square-bracket approach to refer to JSON data:

* def temp = { 'a.b': 'xxx' }
* temp['a.b'] = 'yyy'
* match temp == { 'a.b': 'yyy' }

# using embedded expressions
* def val = 'yyy'
* def temp = { 'a.b': '#(val)' }
* match temp == { 'a.b': 'yyy' }
