Json Jolt - Shifting data to multiple sub-arrays - json

Question

I am trying to do a number of shifts to copy some data into multiple arrays and I am having trouble getting the data to correct array.
This is what I have
{
"input": {
"rating_date": "2018-08-06",
"Rates": {
"name": "Generic ratings Card",
"version": "v1",
"value": "2600.00",
"name1": [
{
"hits": "321",
"genre": "fiction",
"ratingName": "name1"
},
{
"hits": "654",
"genre": "fiction",
"ratingName": "name1"
}
],
"name2": [
{
"hits": "123",
"genre": "nonfiction",
"ratingName": "name2"
},
{
"hits": "456",
"genre": "fiction",
"ratingName": "name2"
}
]
}
},
"spec": {
"operation": "shift",
"spec": {
"rating_date": "rating_by_date[#0].date",
"Rates": {
"name*": {
"$": "rating_by_date[#2].ratecards[#1].type",
"*": {
"#": "rating_by_date[#3].ratecards[#2].rates[#0].&"
}
}
}
}
},
"expected": {
"rating_by_date": [
{
"date": "2018-08-06",
"ratecards": [
{
"type": "name1",
"rates": [
{
"hits": "321",
"genre": "fiction",
"ratingName": "name1"
},
{
"hits": "654",
"genre": "fiction",
"ratingName": "name1"
}
]
},
{
"type": "name2",
"rates": [
{
"hits": "123",
"genre": "nonfiction",
"ratingName": "name2"
},
{
"hits": "456",
"genre": "fiction",
"ratingName": "name2"
}
]
}
]
}
]
}
}
The idea is to take the objects in the rates array and transform them (in a later shift) into Key-Value pairs, which I already know how to do.
Now, the spec I have is not shifting the data into appropriate arrays and I end up with something like this:
{
"rating_by_date" : [ {
"date" : "2018-08-06",
"ratecards" : [ {
"type" : "name1",
"rates" : [ {
"0" : {
"hits" : "321",
"genre" : "fiction",
"ratingName" : "name1"
}
} ]
}, {
"rates" : [ {
"1" : {
"hits" : "654",
"genre" : "fiction",
"ratingName" : "name1"
}
} ]
} ]
}, {
"ratecards" : [ {
"type" : "name2",
"rates" : [ {
"0" : {
"hits" : "123",
"genre" : "nonfiction",
"ratingName" : "name2"
}
} ]
}, {
"rates" : [ {
"1" : {
"hits" : "456",
"genre" : "fiction",
"ratingName" : "name2"
}
} ]
} ]
} ]
}
Instead of creating new objects in the same array, it is creating new arrays altogether. I am clearly not understanding exactly how to reference array structures on the RHS, I'd appreciate a clarification.

I managed to get it to work, but I'm not sure why it would not work in one shift step. Here is what I had to do to make it work:
[
{
"operation": "shift",
"spec": {
"rating_date": "rating_by_date[0].date",
"Rates": {
"name*": {
"$": "rating_by_date[0].ratecards.&.type",
"#": "rating_by_date[0].ratecards.&.rates"
}
}
}
},
{
"operation": "shift",
"spec": {
"rating_by_date": {
"*": {
"ratecards": {
"*": {
"#": "rating_by_date[&3].ratecards2[]"
}
},
"*": "rating_by_date[&1].&"
}
}
}
}
]
