How to find dynamic key values in Karate? - karate

Question

I am hitting JIRA API to fetch cycle id based on cycle name
API : http://localhost:8080/rest/zapi/latest/cycle?projectId=78654&versionId=123
and I am getting following response:
{
"1345": {
"totalExecutions": 0,
"endDate": "",
"description": "",
"versionName": "Unscheduled",
"projectKey": "ABC",
"totalDefects": 0,
"versionId": 123,
"name": "First cycle",
"totalFolders": 0,
"projectId": 78654
},
"5789": {
"totalExecutions": 0,
"endDate": "",
"description": "",
"versionName": "Unscheduled",
"projectKey": "ABC",
"totalDefects": 0,
"versionId": 123,
"name": "Karate DEMO",
"totalFolders": 0,
"projectId": 78654
},
"6543": {
"totalExecutions": 0,
"endDate": "",
"description": "",
"versionName": "Unscheduled",
"projectKey": "ABC",
"totalDefects": 0,
"versionId": 123,
"name": "Second Cycle",
"totalFolders": 0,
"projectId": 78654
},
"recordsCount": 3
}
Here Id's are dynamic i.e. 1345,5789,6543
How do I fetch Id i.e. 5789 where name is "Karate DEMO" using karate jsonpath

Use a JSON transform to change the shape which makes it easier to do JsonPath. You can also find data because karate.forEach() is a "scan": https://github.com/intuit/karate#json-transforms
* def list = []
* def fun = function(k, v){ karate.appendTo('list', { key: k, val: v } )}
* karate.forEach(response, fun)
* def keys = $list[?(#.val.name=='Karate DEMO')].key
