How to control publish rate on topic in ROS2?

[JaydenMomos]

Hi, first of all, great videos on ROS2, extremely helpful! I am working on custom ROS2 messages, and they are successfully built, sourced, Published and Received on the topic/node I create. However, I am not able to record the ros2 bag file for these messages. The error I get each time I try to do it is,
*Failed to record: Something went wrong loading the typesupport library for message type package_name/msgname. Library could not be found.*
Could you possibly guide me through this?
TIA.
