Spring Security 5 настраиваемый фильтр аутентификации

Я беру эту ошибку при установке authenticationFailureHandler: setAuthenticationFailureHandler (authenticationFailureHandler);

java.lang.IllegalArgumentException: failureHandler cannot be null at org.springframework.util.Assert.notNull(Assert.java:193) at org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter.setAuthenticationFailureHandler(AbstractAuthenticationProcessingFilter.java:448)
