I am developing on Rails5 with jQuery. All of a sudden, this afternoon, I started getting these messages in my DevTools console. It happens even running DevTools under StackOverflow. I cleared cache, restarted the browser with no change.
Searching for a solution, I ran across 44315460 When do browsers download sourcemaps? but I don't even know what to do with that.
OBTW, clicking on any of the links generates "ERR_FILE_NOT_FOUND".
I have no idea how this started nor how to fix it. Advice?

missing. I just went to every./path/file.JS
and deleted last line starting with#
which has instructions where the map ought to be. No map request = no warn messages.
