JSON Transformation using JQ - json

Question

I am trying to transform my JSON to different structure using JQ. I am able to partially achieve my new structure, however i get a additional blocks of data.
As i iterate i am able to get the structure in new format. But additional structures are coming.
Code Snippet- https://jqplay.org/s/3gulSlZiWz
JSON
{
"amazon": {
"activeitem": 2,
"createdDate": "2019-01-15T17:36:31.588Z",
"lastModifiedDate": "2019-01-15T17:36:31.588Z",
"user": "net",
"userType": "new",
"items": [
{
"id": 1,
"name": "harry potter",
"state": "sold",
"type": {
"branded": false,
"description": "artwork",
"contentLevel": "season"
}
},
{
"id": 2,
"name": "adidas shoes",
"state": "in inventory",
"type": {
"branded": false,
"description": "Spprts",
"contentLevel": "season"
}
},
{
"id": 3,
"name": "watch",
"state": "returned",
"type": {
"branded": false,
"description": "walking",
"contentLevel": "special"
}
},
{
"id": 4,
"name": "adidas shoes",
"state": "in inventory",
"type": {
"branded": false,
"description": "running",
"contentLevel": "winter"
}
}
],
"product": {
"id": 4,
"name": "adidas shoes",
"source": "dealer",
"destination": "resident"
}
}
}
JQ Query:
.amazon|
{
userType: .userType,
userName: .user,
itemCatalog: {
itemId: .items[].id,
name: .items[].name
}
}
Expected Response:
{
"userType": "new",
"userName": "net",
"itemCatalog": {
"itemId": 1,
"name": "harry potter"
},{
"itemId": 2,
"name": "adidas shoes"
}, {
"itemId": 3,
"name": "watch"
},{
"itemId": 4,
"name": "adidas shoes"
}
}
But getting something weird long duplicated response.

Answer 1

As already pointed out in a comment, the "expected response" is not JSON and probably not what you want anyway. The following would make sense and in any case illustrates how to iterate appropriately:
.amazon
| { userType: .userType,
userName: .user,
itemCatalog: (.items | map({ itemId: .id, name} ))
}
Output
{
"userType": "new",
"userName": "net",
"itemCatalog": [
{
"itemId": 1,
"name": "harry potter"
},
{
"itemId": 2,
"name": "adidas shoes"
},
{
"itemId": 3,
"name": "watch"
},
{
"itemId": 4,
"name": "adidas shoes"
}
]
}
