Hello, this is a known problem related to the command used to build the stack. To prevent this error, please rebuild the stack using catkin_make install (To prevent any weird behavior, I recommend deleting the old build with rm -rf build devel). Once the build is complete, you will have to source the file located in install/setup.bash (instead of the one located in devel). After that you should be able to run the Ned stack without issue.
