I'm getting an issue related with APM Java Agent. My application is a Spring Webflux (Spring Cloud Gateway) and run over Netty framework. Although I can't see any error in debug logs (either in agent or server logs), spans and transactions just don't show up in Kibana APM UI.
Other apps are working fine with agent and generating/collecting spans/transactions using the same version of Java APM Agent. I've already tested with agent 1.7.0 and 1.8.0 versions and I got same behavior.
Logs and screenshots are attached in this topic.
