I think there might be a problem with the expression logic but I'm not sure. I am having trouble with the expressions that refer to there being no answer. For example the expression of turn.KnowledgeAgent?.answer?.length === 0 is giving me problems. It doesn't get triggered even when I check the logs and there is definitely no answer. This was also happening when I used the AI transition and used the logic of "variable is empty" Is this something that anyone else has had issues with?
