I have two questions on user export and import
This is one of user schema

{
    "created_at": "2023-03-13T05:22:17.673Z",
    "email": "any@testmail.com",
    "email_verified": false,
    "identities": [
        {
            "connection": "sampleDB",
            "user_id": "123",
            "provider": "auth0",
            "isSocial": false
        }
    ],
    "name": "any@testmail.com",
    "nickname": "any",
    "picture": "xyz",
    "user_id": "auth0|123",
    "blocked_for": [],
    "guardian_authenticators": [],
     "user_metadata": {
        "userMeta": "data"
    },
    "app_metadata": {
        "mustChangePwd": true
    }

}

This is the curl to export

curl --location 'https: //my-sandbox-2.my-dev.auth0.com/api/v2/jobs/users-exports' \
--header 'authorization: Bearer xyz' \
--header 'content-type: application/json' \
--data '{
    "connection_id": "con_abc",
    "format": "json"
}'

But when I export, it doesn’t give id connections, user meta data and app metadata.Is this expected? Please see the curl above and tell me do I need to explicitly specify each field?

2/ Got 200 ok with job status for user import /api/v2/jobs/users-imports but checking job status I can see it failed to understand more what is error ran this api
curl --location 'https://my-sandbox-2.my-dev.auth0.com/api/v2/jobs/job_abc
–header ‘authorization: Bearer xyz’
but I am getting 204 ok, so I cannot understand really why it failed?
FYI, I am imported same file that it exported earlier,
This is the imported file

{"user_id": "auth0|123","email":"any@testmail.com","name":"any@testmail.com","nickname":"any","created_at":"2023-03-13T05:22:17.673Z","updated_at":"2023-03-13T10:03:09.047Z","email_verified":false}

Any help on what might be wrong with import is greatly appreciated, thanks
