ENV: Ros Melodic on Ubuntu 18.04

Hi,

I am trying to launch my custom nodelet after building it.

after running a catkin_make without any problem and executing roscore followed of

rosrun nodelet nodelet manager __name:=nodelet_manager

And when trying to load my nodelet by running

rosrun nodelet nodelet load quadcopter/Quadcopter nodelet_manager

I received the following error:

[ INFO] [1565186442.980560504]: Loading nodelet /quadcopter_Quadcopter of type quadcopter/Quadcopter to manager nodelet_manager with the following remappings:
[FATAL] [1565186443.003452463]: Failed to load nodelet '/quadcopter_Quadcopter` of type `quadcopter/Quadcopter` to manager `nodelet_manager'

From the terminal where the nodelet manager is running, I received this error:
