straight dump of the error:

I am using move_base_flex for turtlebot3 navigation when I am launching the file got the error. Can anyone please tell me how to solve this error? It's really helpful for me. I tried to find [/robot_state_publisher] where this file is overwritten but I can't.
Check all launch files that you start, and therein the respective node tags. The error message is pretty self-contained. if you want more help from us, you should at least tell us what launch files you are running, and whether they are from a released package or something your crafted yourself. If it is the latter, you need to share the contents of that file...
