Error loading controller issue for running my_doosan_gazebo_controller.launch.py #3

Hi @dvalenciar

I'm trying to make reinforcement learning simulation. Your project is very good for me. However I have some issues in here. I have completed all courses according to the tutorial. However, when I run the model with the last Gazebo connected to the controller, the controller is not loaded and I cannot see any movement in the robot simulation. What part can I fix?

Below is my error code.

I fixed this problem by re-building the ros-controller foxy
