sentinel集成springboot-gateway以及spring-cloud-starter-sleuth时控制台报java.lang.ClassCastException: reactor.core.publisher.FluxLift cannot be cast to org.springframework.core.io.buffer.PooledDataBuffer

sentinel的版本是1.7.0版本
spring-cloud-starter-sleuth版本是通过springcloud的Hoxton.SR3的dependencies控制的2.2.5.Releases版本

Start by reproducing the reported ClassCastException with Sentinel 1.7.0, Spring Cloud Hoxton.SR3, and spring-cloud-starter-sleuth 2.2.5.RELEASE. Inspect org.springframework.cloud.gateway.filter.RemoveCachedBodyFilter at line 37 alongside SentinelReactorSubscriber.java and the shown Reactor callbacks; done means the gateway completes without this exception.
