Error in concatenating Grunt files and minifying CSS files

I encountered an issue while attempting to concatenate and minify CSS using grunt. I included a myPage method/object, but I'm unsure how to initialize it. As a beginner in grunt tasks, I'm trying to learn and tackle this challenge.

Here's what I tried:

Gruntfile.js

module.exports = function(grunt) {
    "use strict";

    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        myPage: {
            concat: {
                css: {
                    src: 'common/css/*.css',
                    dest: 'common/css/concat.css'
                }
            },
            cssmin: {
                css: {
                    src: 'common/css/concat.css',
                    dest: 'common/css/concat.min.css'
                }
            }
        }        
    });
    grunt.registerTask('devbuild', function() {
        grunt.task.run(['concat:css','cssmin:css']);
    });
    grunt.loadNpmTasks('grunt-contrib-concat');
    grunt.loadNpmTasks('grunt-contrib-cssmin');
    grunt.registerTask('build', ['devbuild']);

    grunt.registerTask("default", ["build"]);

};

Changing

grunt.task.run(['concat:css','cssmin:css']);
to
grunt.task.run(['myPage:concat:css','myPage:cssmin:css']);
is necessary in this scenario.

However, it should be noted that having the myPage object may not offer significant benefits in this context.
