Hi,
We are using the ZED_Multi node with ROS2 humble in a launch file where we start several other nodes. Normally the node starts up properly and the topics are published. Sometimes, however, the following error appears. After aborting the launch and running it again, it usually works again.
Are there any improvements we can make to avoid this behavior?
