Source maps are like favicons, a thing that will be loaded by browsers in some circumstances.

Typically, javascript are minified on production servers and debugging javascript on them is difficult.

Source maps are the original versions of minified javascript. It's up to the developers to include them or not on their websites.

In Chrome, you have to activate this functionality for the browser to attempt to download the original non-minified version of a minified script. It is then easier to debug client-side.

Basically, you can't get rid of this error besides providing source maps.
