Grunt usemin Warning: Object has no method 'contains' - grunt-usemin

Question

I am using Grunt task runner, and the Gruntfile.js" is as follows:
'use strict';
module.exports = function(grunt){
require('time-grunt')(grunt);
require('jit-grunt')(grunt, {
useminPrepare: 'grunt-usemin'
});
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
jshint: {
options: {
jshintrc: '.jshintrc',
reporter: require('jshint-stylish')
},
all: {
src: ['Gruntfile.js', 'app/scripts/{,*/}*.js']
}
},
useminPrepare: {
html: 'app/menu.html',
options: {
dest: 'dist'
}
},
concat: {
options: {
separator: ';'
},
dist:{}
},
uglify:{
dist:{}
},
cssmin: {
dist:{}
},
filerev: {
options: {
encoding: 'utf8',
algorithm: 'md5',
length: 20
},
release: {
files:[{
src: ['dist/scripts/*.js', 'dist/styles/*.css']
}]
}
},
usemin: {
html: ['dist/*.html'],
css: ['dist/styles/*.css'],
options: {
assetsDirs: ['dist', 'dist/styles']
}
},
copy: {
dist: {
cwd: 'app',
src: ['**', '!styles/**/*.css', '!scripts/**/*.js'],
dest: 'dist',
expand: true
},
fonts: {
files: [
{
expand: true,
dot: true,
cwd: 'bower_components/bootstrap/dist',
src: ['fonts/*.*'],
dest: 'dist'
},
{
expand: true,
dot: true,
cwd: 'bower_components/font-awesome',
src: ['fonts/*.*'],
dest: 'dist'
}
]
}
},
clean: {
build:{
src: ['dist/']
}
}
});
grunt.registerTask('build', ['clean', 'jshint', 'useminPrepare', 'concat', 'cssmin', 'uglify', 'copy', 'filerev', 'usemin']);
grunt.registerTask('default', ['build']);
};
The problem is that when the grunt is executing usemin, it shows the following warning and aborts the task:
I cannot figure out exactly where the problem is and therefore I don't know how many more codes do I have to give. I am a beginner.
Update:
here is my own script that I used in the project:
'use strict';
angular.module('confusionApp', []).controller('menuController', function(){
var dishes=[

}
];
this.dishes = dishes;
this.tab = 1;
this.filtText = '';
this.select = function(setTab){
this.tab = setTab;
if(setTab === 2){
this.filtText = "appetizer";
}
else if(setTab === 3){
this.filtText = "mains";
}
else if(setTab === 4){
this.filtText = "dessert";
}
else{
this.filtText = "";
}
};
this.isSelected = function(isTab){
if(this.tab === isTab){
return true;
}
return false;
};
});
Update
This is the stack trace of the error that I got.

The problem lies with the usemin version that you are using. It turns out, changing your usemin version from 3.1.1 to 3.0.0 in your package.json solves the problem. My best bet is that there is no problem with your code but with the fileprocessor.js file in your usemin. Changing the version solves the problem.
Change usemin version on your package.json and run npm install.
