Keycloak API - update user call returns 409 Conflict


I would like to update user and update his password. I use one PUT call with body:

  "username": "",
  "email": "",
  "credentials": [
      "type": "password",
      "value": "1111!"

The keycloak returns “409 Conflict” because password policy requires additional symbols. However “username” and “email” have been updated.
I don’t need “partial update”. Is it possible to configure keycloak somehow to use atomic updates?
