Our technology stack is spring webflux. To support Elastic APM, we use the elastic apm bridge and opentracing-spring-cloud-starter. Works very well in the following versions:
elasticsearch version: 5.x
apm agent version: 1.6.1
apm opentracing version: 1.6.1
opentracing-spring-cloud-starter version: 0.2.6
Due to company's elasticsearch version upgrade to 6.6.5，the agent version 1.6.1 is not fit.
so we upgrade the version of agent. However there is no version compatible between agent and opentracing-spring-cloud-starter. Either there is no span, or service startup error with reporting no class method.
I have no idea how to do.
