Missing map resource

Question

I ve recently started having this problem with all my projects   When my index page loads which contains a reference to the jquery source file  my console logs this error  GET http   localhost 3000 js lib jquery-1 10 2 min map 500  Internal Server Error    This doesn t affect my application at all  but it s really annoying to see whenever I open up the console   Does anyone know where this is coming from   Edit  Note that I m not explicitly referencing the  map file  I am just pointing to  lt script src  js lib jquery-1 10 2 min js  gt  lt  script gt

I had similar expirience like yours  I have Denwer server  When I loaded my http   new new local site without using via script src jquery min js file at index php in Chrome I got error 500 jquery min map in console  I resolved this problem simply - I disabled extension Wunderlist in Chrome and voila - I never see this error more  Although  No  I found this error again - when Wunderlist have been on again  So  check your extensions and try to disable all of them or some of them or one by one  Good luck

jQuery recently started using source maps   For example  let s look at the minified jQuery 2 0 3 file s first few lines       jQuery v2 0 3    c  2005  2013 jQuery Foundation  Inc    jquery org license     sourceMappingURL jquery min map      Excerpt from Introduction to JavaScript Source Maps      Have you ever found yourself wishing you could keep your client-side   code readable and more importantly debuggable even after you ve   combined and minified it  without impacting performance  Well now you   can through the magic of source maps       Basically it s a way to map a combined minified file back to an   unbuilt state  When you build for production  along with minifying and   combining your JavaScript files  you generate a source map which holds   information about your original files  When you query a certain line   and column number in your generated JavaScript you can do a lookup in   the source map which returns the original location  Developer tools    currently WebKit nightly builds  Google Chrome  or Firefox 23   can   parse the source map automatically and make it appear as though you re   running unminified and uncombined files     emphasis mine  It s incredibly useful  and will only download if the user opens dev tools   Solution  Remove the source mapping line  or do nothing   It isn t really a problem     Side note  your server should return 404  not 500   It could point to a security problem if this happens in production
