Converting array to objects within an object - json

Question

I have been battling with this for sometime, ive looked a few articles in regards to this topic. I can't seem to get exactly what I'm aiming for. I have this original json data that I would like to transform a bit.
Group the objects based on the label.env (for now only using one env), then inserting those objects from the original json into an object named projects.
orginial_json
{
"createTime": "2020-06-25T14:16:45.720Z",
"labels": {
"cb_domain": "cloud-services",
"cb_product": "infra",
"env": "prod",
"owner": "cloud-server"
},
"lifecycleState": "ACTIVE",
"name": "projectname",
"parent": {
"id": "123456577",
"type": "folder"
},
"projectId": "projectname-324234",
"projectNumber": "962363417856"
}
{
"createTime": "2020-06-24T19:45:42.851Z",
"labels": {
"cb_domain": "cloud-services",
"cb_product": "ad",
"env": "prod",
"owner": "cloud-server"
},
"lifecycleState": "ACTIVE",
"name": "projectname2",
"parent": {
"id": "4352564765437",
"type": "folder"
},
"projectId": "projectname2-4567",
"projectNumber": "3243456324"
}
Im using jq -s 'group_by(.labels.env) | .[] | { (.[0].labels.env) : { projects: .[] | . } }'
to nest the original json data into objects grouped by env\projects, which works but seems to duplicate it instead of putting each object within projects.
{
"prod": {
"projects": {
"createTime": "2020-06-25T14:16:45.720Z",
"labels": {
"cb_domain": "cloud-services",
"cb_product": "infra",
"env": "prod",
"owner": "cloud-server"
},
"lifecycleState": "ACTIVE",
"name": "projectname",
"parent": {
"id": "770593713153",
"type": "folder"
},
"projectId": "projectname-324234",
"projectNumber": "962363417856"
}
}
}
{
"prod": {
"projects": {
"createTime": "2020-06-24T19:45:42.851Z",
"labels": {
"cb_domain": "cloud-services",
"cb_product": "ad",
"env": "prod",
"owner": "cloud-server"
},
"lifecycleState": "ACTIVE",
"name": "projectname2",
"parent": {
"id": "4352564765437",
"type": "folder"
},
"projectId": "projectname2-4567",
"projectNumber": "3243456324"
}
}
}
What I'm aiming for is
{
"prod": {
"projects": {
"createTime": "2020-06-25T14:16:45.720Z",
"labels": {
"cb_domain": "cloud-services",
"cb_product": "infra",
"env": "prod",
"owner": "cloud-server"
},
"lifecycleState": "ACTIVE",
"name": "projectname",
"parent": {
"id": "770593713153",
"type": "folder"
},
"projectId": "projectname-324234",
"projectNumber": "962363417856"
},
{

"labels": {
"cb_domain": "cloud-services",
"cb_product": "ad",

}
}
}

Allowing for some minor discrepancies in the Q, the following variant of your jq program seems to do what you're trying to achieve:
group_by(.labels.env)
| .[]
| .[0].labels.env as $key
| { ($key) : { projects: . } }
