Create user endpoint doesn't set email, groups and roles

Hi,

I’m  using looker api v3.1. I’m trying to create a user with “POST/api/3.1/users” endpoint. It returns successful, but it doesn’t set user’s email, groups and roles. Email and roles are returning as null, groups field is not what I’ve sent.

Am I missing something? My request and responses are below:

Request:

{
  "email": "sample@email.com",
  "first_name": "Jhon",
  "is_disabled": false,
  "last_name": "Doe",
  "group_ids": [3],
  "role_ids": [5],
  "credentials_email": {
      "email": "sample@email.com",
      "is_disabled": false,
      "type": "email",
      "forced_password_reset_at_next_login": false
  }
}
