Message type (yolo_msgs/msg/DetectionArray) is invalid

[mrrmgee]

I have everything set up and I have yolo running with object detection in Rviz with my laptop webcam. When I try and look at the topic data for some yolo topics it gives me a message type is invalid error. I am on ROS2 Humble and using usb-cam for my camera.

@mrrmgee just to confirm, can you visualize the detections in rviz2? If yes, the invalid problem may be due to the fact that you have not source your install directory in your workspace.
