研究方向
Investigate the NullPointerException in SentinelReactorSubscriber.currentContext at line 70 in the reactor adapter module. The stack trace indicates a null value being passed to Context2.put. Check if the issue is due to a null entry in the context or a missing null check. Consider replicating with Spring Cloud Gateway 3.1.4 and Sentinel 1.8.6 and examine the currentContext method flow.
