Api/beta/get-account: unknown attributes

Hello there,

Does anyone know why the following attributes are returned by the get-account | SailPoint Developer Community API call?
I expected only to receive id, name and triggered, as these are the fields that I’ve configured for the CSV source.
Not even sourceId should be there, right?

    "attributes": {
        "mantisExecutor": "com.sailpoint.mantis.identity.task.AggregateIdentityTask",
        "sourceId": "09bb0deb5e4d411d8d5468c013cf5527",
        "serviceClass": "sailpoint.thunderbolt.service.IdentityService",
        "triggered": "2024-04-22T08:22:38.219Z",
        "name": "999001",
        "id": "999001",
        "idNowDescription": "76c48640b6ee3f080b000b2197bcbeda32aa4ca334a72cfd7e910a387bdd93e0",
        "serviceMethod": "createTask"
    },

Am I reading the documentation wrong?

Best regards,
Andrei
