Karate loop returns Json array as objects {} - testing

Question

I'm using Karate loops to generate dynamic Json.
One of my test data contains array within an object. When I use karate loop on this data, the array is returned as an object.
* def fun = function(i){ return { "name": "userName"+ i, "email": "Tester#test.com", "id": "ID"+i, "testSheet": [{"sheetId" : "123"}]} }
* def jsonBody = karate.repeat(3, fun)
* print jsonBody
I'm expecting below:
[
{
"name": "userName0",
"email": "Tester#test.com",
"id": "ID1",
"testSheet": [
{
"sheetId": "123"
}
]
}
]
But it returns this
[
{
"name": "userName0",
"email": "Tester#test.com",
"id": "ID1",
"testSheet": {
"0": {
"sheetId": "123"
}
}
}
]
Expected path: jsonBody[0].testSheet[0].sheetId
Actual path: jsonBody[0].testSheet.0.sheetId

Unfortunately this is a bug, which will be fixed in the next release: https://github.com/intuit/karate/issues/1187
This is the work-around. Define the array part outside the JS block for now, and use copy:
* def testSheet = [{"sheetId" : "123"}]
* def fun = function(i){ return { "name": "userName"+ i, "email": "Tester#test.com", "id": "ID"+i, "testSheet": testSheet } }
* copy jsonBody = karate.repeat(3, fun)
* print jsonBody
