"roslaunch blue_bringup right.launch param_file:=blue_params.yaml" is not running.

I got error saying that "REQUIRED process [right_arm/blue_controller_manager-2] has died!"

I thought this is happening because I am using the wrong config file, so I tried the following two but both not working.

• "blue_bringup>config>robot_parameters_right.yaml"
• "blue_config>blue_right_v2.yaml"

FYI. I am using following setting.
OS: Ubuntu 18.04
ROS dist: Melodic
