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?

For me it helped to only enable current context in devtools.
Caveat: It is not sticky. You have to reset it every time you open DevTools.
Caveat: API calls to other domains won't show any errors as they belong to a different context.
