Field login_name is empty after create an user

[Gitttttttt]

Description

When I create an user, I found the login_name is empty. My request like this:
curl -X 'POST' \ 'https://x.x.x.x:8080/api/v1/admin/users' \ -H 'accept: application/json' \ -H 'authorization: Basic xxxxxxxxx' \ -H 'Content-Type: application/json' \ -d '{ "created_at": "2024-04-16T01:56:42.453Z", "email": "test3@example.com", "full_name": "test3", "login_name": "test3", "must_change_password": false, "password": "aaaa@2024", "restricted": true, "send_notify": true, "source_id": 0, "username": "test3", "visibility": "public" }'

But the result like this:
