SearchCondition for ManagedBaseline

I'm working on some code in a workflow and I want to be able to query baselines that meet certain conditions. When I use syntax like the below, the workflow goes to an "aborted" state with no indication as to why.  How would I query baselines?

wt.query.SearchCondition sc = new wt.query.SearchCondition(wt.vc.baseline.ManagedBaseline.class, "lifeCycleState", wt.query.SearchCondition.EQUAL, "Approved", false);
