Also, what do you think would be a good way of publishing an array of geometry_msgs::Point?. From time to time I got a Segmentation Fault in my Robot Ros node, but most of the time nothing happens. Using the empty arrays gains the benefit of not needing to send the empty data fields. In RViz for ROS 2 the frames transformation library is now pluggable, meaning that different transformation library plugins can be loaded and changed dynamically in the gui. When the bus is converted to a ROS message, FrameId is converted back to a string. Row-level security (RLS) with Power BI can be used to restrict data access for given users. I can send an array of strings just fine, but receiving one causes a segfault— seems like the length of the string is getting garbled up with the length of the array, and the part of the deserializer that shifts the string over to make room for a null is making a big mess.
