JavaScript Source maps "not used"

Hey,

any hints how to debug why JavaScript source maps are not “working” in my actual setup?
The source maps get generated by gulp, in Chrome they are enabled (scss source maps are working…), the comment is present in the uglified dist js file, but Chrome does not apply the source map…

I am on Max OS X 10.10.4 and Chrome 43.0.2357.132.

Thanks

Maybe try another browser too? Firefox dev edition would be a good test. Not saying you need to use another browser but it might help troubleshoot to see where the issue is.

I’d found a solution to this in a similar issue a while back: Sourcemaps no longer working as expected with Sage update - hopefully it works for you!
