Cannot load message class for [roboclaw/RoboclawEncoderSteps]

edit

Hello,

I'm trying to get joy teleop working with a Roboclaw motor controller.

I'm using this node to interface with the controller.

https://github.com/csvance/roboclaw

Current setup:

ROS Melodic Jetson Nano Roboclaw 2x15 Motor controller

While troubleshooting I'm unable to rostopic echo /motor_enc. I'm getting the following error.

rostopic echo /motor_enc
ERROR: Cannot load message class for [roboclaw/RoboclawEncoderSteps]. Are your messages built?

catkin_make compiled the project successfully with no errors.

I'm using AMT10 quadrature encoders and I'm able to see the counters increase or decrease with BasicMicroMotionStudio software. I've tried lowing the encoders PPS settings to the lowest available resolution. Current resolution settings are at 48 pulses a second which gives me around 482 steps per meter.

Has anyone encountered this issue before? I'm a beginner with ROS and I'm not sure where to start looking. I would really appreciate anyone's assistance with this issue.

This is the launch file i'm using.
