Are you using Vue.js? If so, you might need to install this: https://github.com/vuejs/vue-devtools

If you're using WebEssentials, you might want to look at this as well:

Google Chrome "Failed parsing SourceMap" : css.map (Web Essential)

If you get this type of error:

"DevTools failed to parse SourceMap:../js/popper.min.js.map"

or something like this, then go to Developer Tools -> Settings and untick

  1. "Enable JavaScript source maps"

  2. "Enable CSS source maps"

example

    Actually you need to go into Dev Tools settings and you will see the above options. It was very frustrating to search this in the Browser settings! – KoolPal Apr 07 '20 at 14:44

    It doesn't fix the warnings, just hides it. Mozilla has some more information about it here https://developer.mozilla.org/en-US/docs/Tools/Debugger/Source_map_errors. – DevonDahon May 06 '20 at 20:45

I received this error:

DevTools failed to load SourceMap: Could not load content for chrome-extension://gighmmpiobklfepjocnamgkkbiglidom/include.preload.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME

Then i went to my chrome extensions on chrome://extensions/

and found an extension with the code 'gighmmpiobklfepjocnamgkkbiglidom' on my case.

Then i turned it off.

If you want to keep the extension working you can just filter this message on DevTools as in:

Dev tools filter image

Hope it helps!

If they are just unimportant warnings that are bothering you when leaving the console, you can temporarily disable them (menu option accessed via F12 key):
