[elasticloadbalancingv2] Exception in addTargetGroups when using conditions prop only

[AnatolyUA]

At the moment I'm using this code to add a Target Group to ALB (java):

mainLBListener.addTargetGroups("EchoLambdaTg", AddApplicationTargetGroupsProps.builder().priority(100)
                                .conditions(List.of(ListenerCondition.pathPatterns(List.of("/links*"))))
                                .pathPattern("/links*").targetGroups(Collections.singletonList(tg)).build());

As I can understand pathPattern is @deprecated Use 'conditions' instead.. But when I remove it:

mainLBListener.addTargetGroups("EchoLambdaTg", AddApplicationTargetGroupsProps.builder().priority(100)
                                .conditions(List.of(ListenerCondition.pathPatterns(List.of("/links*"))))
                                .targetGroups(Collections.singletonList(tg)).build());

I get this exception:

An exception occured while executing the Java class. At least one of 'conditions', 'hostHeader', 'pathPattern' or 'pathPatterns' is required when defining a load balancing rule.
