I'm using gulp-usemin for minify the javascript files I use in my app, for some reason gulp is not seeing one of my files. I have this in my index.html:
<body ng-app="App">

And this is my gulpfile.js:

gulp.task('build', ['build-assets','copy-templates', 'usemin']);
gulp.task('default', ['build', 'zip']);
gulp.task('run', ['build', 'webserver', 'livereload', 'watch']);
When I run default task I get this message:
TypeError: Path must be a string. Received undefined
If I remove <script src="scripts/directives/directive2/directive2.js" type="text/javascript"></script> from the index the gulp task run without errors and I'm pretty sure the file is there and url is written correctly.
Please help!!
The solution I found is passing
{mangle:false}to 'gulp-uglify' constructor, in my case replaceMore information in this post: Gulp ngmin + uglify not working properly
