i'm actualy coding my website and using the devtool for debbugging, and i find out that the adblock extention give me the error of javascript map
as bellow
DevTools failed to load source map: Could not load content for chrome-extension://cfhdojbkjhnklbpkdaibdccddilifddb/browser-polyfill.js.map: System error: net::ERR_FILE_NOT_FOUND
i have to disable this extension to prevent me to have this error.
so i think you have forgot to delete some path in your code. thanks-you
