### Question
- What do you want to know?
currently, skywalking seems not to support spring-cloud-gateway 3.0. If
using apm-spring-cloud-gateway-2.1.x-plugin-8.4.0.jar plugin with
spring-cloud-gateway 3.0, it throws java.lang.NullPointerException while
receive a request.
the exception stack is as follow:
```
