  1. Please describe the issue in detail.

    I am working with gazebo simulation, an trying to make a map with slam and run the navigation. whenever i save the map outside of the turtlebot3_navigation directory I get the same error, i try to launch the map server to publish the map with rosrun map_server map_server path/map.yaml then the problem with the map is resolved but the navigation can't get to the /scan topic publication. when i save the map in the directory of the navigation package, everything seems to go fine. I really need to save the maps somewhere else!

Please make sure that the map image as well as the map .yaml files are both at the same location i.e. in the same folder/depth of the workspace.

Hi @aslanko1992.
This command error can occur if the file location is not set correctly.
Please check that the file path is accurate.
Let me know if any issues arise. Thank you.
