The passed action type is invalid

[sudomuho1]

Good day,

I have followed all the steps, and when I run on of the commands:
ros2 action send_goal -f /MoveROT ros2_data/action/MoveROT "{yaw: 0.00, pitch: 0.00, roll: 0.00, speed: 1.0}"

It gives an error about the passed action type is invalid. What could be the reason for it?

Maybe you should use "soure install/setup.bash" before you run the command
