Custom App with Gazebo Simulator does not Work


I’ve tried to create the GzWeb as a custom app. So I built an environment that includes the gazebo simulator and SSH. My goal is to open GzWeb in my browser and connect to its environment in the running time via SSH from my local machine. Then when I tried to launch that custom app, it didn’t work. I think it crashed every time I tried to launch it. And I can’t see the launching log to find the issue.
