Description

我使用的版本是2.10.6,springboot版本2.7.11,执行到AopInvocationHandler.invoke方法时,入参args为null,导致触发空指针异常

java.lang.ClassCastException: java.lang.NullPointerException cannot be cast to java.lang.reflect.InvocationTargetException

Research direction

Start by reproducing the failure with LiteFlow 2.10.6 and Spring Boot 2.7.11, then inspect ComponentProxy.java at AopInvocationHandler.invoke (around line 238) and the Node.execute call path. Determine why a null args value reaches the handler; done means the reported invocation no longer throws the null-pointer-related exception.
