Spring Sleuth + Zuul = java.lang.IllegalArgumentException: Malformed id

Question

We are using spring-cloud-sleuth together with spring-cloud-zuul.

In above case when HTTP request is forwarded from Spring Zuul to next micro-service X then on X we get following error:

java.lang.IllegalArgumentException: Malformed id: 6103370e80268685, 6103370e80268685

Why does it happen only when we forward messages from ZUUL to other micro-services but it does not occur in communication between other micro-services in our system?

Answer 1

It was a bug which is already fixed.

But feature does not work on:

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR4</version>

As temporary solution you can turn it off on ZUUL until next release:

spring.sleuth.zuul.enabled: false
