Pretty much what the topic line says

@Darshit-Desai Hi, wondering if you were able to solve this.

@Darshit-Desai are your ROS_ID's the same between the docker and disk? If not how are you sharing the interfaces into the ros docker instance?

If it is easier you can just share the /opt/ros/foxy/mpa_to_ros2 directory as a volume as well as the /run/mpa directory as a volume and run the ros2 node in the docker instance. The other thing to note is I am unsure if there is compatibility between foxy and humble in terms of the nodes or if there are some internal conflicts happening behind the scenes.

@Zachary-Lowell-0 I am not sure how I resolved this, but as far as I remember there was px4_msgs versioning issue where I wasn't using either the correct ones or something
