I've recently started working in a Browserify built Javascript app that uses source maps with ReactJs and I haven't been able to get Chrome's Workspace to work. I'm following the same steps I used in my previous AngularJs app that wasn't using source maps
After doing this I get the error below.
Source map http://localhost/B2BMessageRunner/WebApp/build/scripts/bundle/app.js points to the files missing from the workspace: [http://localhost/B2BMessageRunner/WebApp/build/scripts/bundle/c:\code\B2B.MessageRunner\MessageRunner.Web.Ux\WebApp\app\scripts\config\Config.js]
Note that the bundle/scripts/bundle directory is where my mapped JS file gets copied too.
I had the same issue with the standard Chrome but it works on the last Chrome Canary.
