   ### Question
   - What do you want to know?
   
   can skywalking work with envoy directly?
   
   ### Which version of SkyWalking, OS and JRE?
   6.4.0
   
   in k8s
   
   use official docker image
   
   ### my setup step
   1. enable the zipkin receiver in skywalking-oap env
   1. set the envoy zipkinAddress to skywalking-oap:9411
   1. change the skywalking-ui timezone
   
   ### problem
   get the trace list in skywalking ui with trace id ,start time and duration.
   
   but cannot get the trace detail,i find the error in skywalking-oap log
   
   ```
