You are a container engineer at Cube4Lyf, an e-gaming platform geared towards puzzle and logic games. One of the pods running a newly launched game is failing. You need to identify the error causing the pod to fail and to extract the error for the logging agent to pick up so the developers, who don't have access to this environment, can view the error and create a patch.
