please help me
Hello MS_Farhan,
The error means that file /rosbot_conf.yaml can not be found. This file should be added by setup_ROSbot_for_gg.sh script mentioned in Device setup step from manual. Did this script execute properly?

The deployment is configured to operate in Husarnet network with ROSbot and EC2 instance. If you want your PC to receive messages from these devices, you need to install Husarnet on your PC.
curl https://install.husarnet.com/install.sh | sudo bash
echo "export ROS_IPV6=on" >> ~/.bashrc
echo "export ROS_MASTER_URI=http://master:11311" >> ~/.bashrc
Then add your PC to the same network, which ROSbot and EC2 were added.
sudo husarnet websetup
Regards,
Łukasz
