Keycloak 15.0.0 Cannot list realms using keycloak-admin-client

Configuring the server
,
1

Using the maven dependency keycloak-admin-client, I cannot list realms :

        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-admin-client</artifactId>
            <version>15.0.0</version>
        </dependency>

val realms = keycloak.realms().findAll()

I get this error :

com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: 
Unrecognized field "oauth2DeviceCodeLifespan"

javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: 
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: 
Unrecognized field "oauth2DeviceCodeLifespan" (class org.keycloak.representations.idm.RealmRepresentation), not marked as ignorable 
(130 known properties: "userFederationMappers", "rememberMe", "duplicateEmailsAllowed", "adminEventsDetailsEnabled", "users", "clientOfflineSessionMaxLifespan", "webAuthnPolicyRequireResidentKey",

On the server side, no log is written.

I’m using Keycloak server 15.0.0 and keycloak-admin-client 15.0.0
