[keycloak-user] Realm.toRepresentation results in com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException

Hello, I'm using the java admin client to create a realm and some other setting. In this process I like to update the realm (set authentication bindings for registration flow and credential flow) therefore I from my actual knowledge have to transfer the realm to the realm representation. Doing this calling realm.toRepresentation() results in the following error: javax.ws.rs.client.ResponseProcessingException: javax.ws.rs. ProcessingException: com.fasterxml.jackson.databind.exc. UnrecognizedPropertyException: Unrecognized field " offlineSessionMaxLifespanEnabled" (class org.keycloak.representations.idm. RealmRepresentation), not marked as ignorable (101 known properties: " directGrantFlow", "otpPolicyDigits", "identityProviderMappers", " revokeRefreshToken", "identityProviders", "userFederationMappers", " rememberMe", "duplicateEmailsAllowed", "dockerAuthenticationFlow", " otpSupportedApplications", "adminEventsDetailsEnabled", "registrationFlow", "editUsernameAllowed", "clients", "users", "emailTheme", "realm", " actionTokenGeneratedByAdminLifespan", "authenticatorConfig", "components", "certificate", "updateProfileOnInitialSocialLogin", "otpPolicyType", " accessCodeLifespanUserAction", "protocolMappers", "id", "accountTheme", " maxDeltaTimeSeconds", "enabledEventTypes", "verifyEmail", "applications", " waitIncrementSeconds", "eventsListeners", "eventsExpiration", " defaultDefaultClientScopes", "defaultOptionalClientScopes", "passwordPolicy", "clientTemplates", "registrationAllowed", "userManagedAccessAllowed", " notBefore", "otpPolicyAlgorithm", "actionTokenGeneratedByUserLifespan", " permanentLockout", "socialProviders", "otpPolicyInitialCounter" [truncated]]) Can you pleas give me a hint how to resolve this? Thanks in advance. Andreas
