Screenshot of the error
Error details
Exercise 2.3: I tried to configure the map display according to the screenshot in course notebook, but it still says "No map received"
If I do: ros2 topic echo /map I do get something back, and the header looks correct.

Hello did you have choosen correctly reliability and durability policy?
This is the reliability and durability policy I have, I tried to use the same as shown in course notebook.
Ok, since you have the correct QoS settings, what you can do is:
Confirm that the map_server
ran correctly and provided the map (I assume it did because you metion you are able to echo /map
)
Uncheck/check the actual “Map” element in rviz2
. Since the map server only publishes once, sometimes rviz2
might not catch it.
Restart the map server with rviz2
launched
Thanks a lot for the hints!
Starting rviz before map_server solved the problem.
