Are you trying to run this locally? This works well from the Docker. Are you sure you performed the other necessary setups including environment variables and typed the exact command, e.g., /opt/ros/iron/setup.sh && . /usr/local/webots-project/controllers/participant/install/setup.sh && ros2 launch participant robot_launch.py?
