Error SourceMap after build by custom-build of Polymer.

[roniny-afk]

I guess "intl-messageformat" has been bundled in build file
therefore browser can not call SourceMap.

Example : Failed to parse SourceMap: http://localhost:8080/src/intl-messageformat.min.js.map

Sorry to Problem.

I'm not sure I understand the problem. I can't access your localhost :(
