Easy Travel Loadgen problem simulation

Hello,

I'm experiencing an issue deploying the EasyTravel environment via Docker on an EC2 instance (Amazon Linux).

All services start correctly with docker compose up, and the containers (frontend on ports :80, :8080, and :9079) are accessible. Data is successfully reported to Dynatrace.

However, the loadgen container consistently fails to start with the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper
at ch.qos.logback.contrib.jackson.JacksonJsonFormatter.<init>(Unknown Source)
...
Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.ObjectMapper
 

This is blocking me because it doesn't generate problems. What modification can be made to correct this and simulate problems?
