I have a custom ROS2 message, which I built and sourced correctly and it successfully publishes and subscribes on the node I create. However, when I try to record the bag files using

ros2 bag record -topicname

it throws this error,

Failed to record: Something went wrong loading the typesupport library for message type package_name/msgname. Library could not be found.

I don't know why this error, is it because it is a custom message? Or is it because I need to link the custom messages somewhere?

I played around a bit myself with this, if you've properly sourced the package with the ROS2 message, there shouldn't be any issues. I tried running ros2 bag without sourcing the ROS2 message being published, but I don't get this error, it just hangs listening for topics.

If you are properly sourced, ros2 topic echo /your_topic should work. Otherwise, this might be a bug.
