Hi,

When i use open zipkin and kafka, i got an error side zipkin collector, here is the stack trace, can someone face to the same issue ?

interesting.. looks like it couldn't read the trace id. how are you serializing/reporting spans to kafka? Did this just recently break in 1.20 or has this never worked for you.

Hi,

It's my first time to test openzipkin with kafka, i follow this tutorial for producing events: https://blog.codecentric.de/en/2016/04/event-driven-microservices-spring-cloud-stream/

And i use openzipkin for consuming events

[codefromthecrypt]

this is a known issue.. you can't receive spans issued by spring-cloud-stream over kafka with the basic zipkin server. you have to run https://github.com/spring-cloud/spring-cloud-sleuth/tree/master/spring-cloud-sleuth-zipkin-stream

Once https://github.com/spring-cloud/spring-cloud-sleuth/issues/253 is complete, you should be able to use normal zipkin for this.
