If we disable minification then the error goes away and it exports successfully. So seems to be minify problem with the aurelia-bundler. We are using v0.5.0 bundler.

Please go through this https://github.com/mishoo/UglifyJS2/issues/348 and make sure that there isn't any error in code that is causing this. This seems to be a UglifyJS error and Aurelia can do little to help it, but we can try.
