I am unable to save .rviz file . I am following the instructions in the lesson and choosing Save As option but Everytime, I get an error saying could not open and write the file. How can I fix this?
What directory were you attempting to save it to? Were you saving it somewhere inside catkin_ws? Otherwise, the site’s security settings will prevent the save.
Thanks a lot @chrisc65ca1771ca646bb . I went to the path inside catkin_ws and it worked. Thanks a lot
