Issue when running grunt build

[angra8410]

Good day, This is my first help cry, cause I am stuck trying to run the Grunt build for my project, this is the error I have: jit-grunt: Plugin for the "UseminPrepare" task not found. and this is my Gruntfile: const { registerTask } = require("grunt");

module.exports =function (grunt){ require('time-grunt')(grunt); require('jit-grunt')(grunt,{ useminprepare: 'grunt-usemin' }); grunt.initConfig({ sass: { dist: { files: [{ expand: true, cwd: 'css', src: ['*.scss'], dest: 'css', ext: '.css' }] } },

    watch: {
        files: ['css/*.scss'],
        tasks: ['css']
    },
    
    browserSync: {
        dev: {
            bsFiles: { //browser files
                src: [
                    'css/*.css',
                    '*.html',
                    'js/*.js',
                ]
                },
        options: {
            watchTask: true,
            server: {
                baseDir: './' //Directorio base para nuestro servidor
                }
            }
        }
    },

    imagemin: {
        dynamic: {
            files: [{
                expand: true,
                cwd: './',
                src: 'images/*.{png,gif,jpg,jpeg}',
                dest: 'dist/'
            }]
        }
    },

    copy: {
        html: {
            files: [{
                expand: true,
                cwd: './',
                src: 'images/*.{png,gif,jpg,jpeg}',
                dest: 'dist',
            }]
        },
    },

    clean: {
        build:{
            src: ['dist/']
        }
    },

    uglify: {
        dist: {}
    },

    filerev: {
        options: {
            encoding: 'utf-8',
            algorith: 'md5',
            length: 20
        },
    
    release: {
        // filerev: release hashes(md5) all assets (images, js and css )
        // in dist directory
            files: [{
                src: [

                ]
            }]
        }
    },

    concat: {
        options: {
            separator: ';'
        },
        dist: {}
    },

    useminprepare: {
        foo: {
            dest: 'dist',
            src: ['index.html', 'about.html', 'precios.html', 'contactanos.html', 'Términosycondiciones.html'],
        },
        options: {
            flow: {
                steps: {

                },
                post: {
                    css: [{
                        name: 'cssmin',
                        createConfig: function(context, block){
                            var generated = context.options.generated;
                            generated.options ={
                                keepSpecialComments: 0,
                                rebase: false
                            }
                        }
                    }]
                }
            }
        }
    },

    usemin: {
        html: ['dist/index.html', 'dist/about.html', 'dist/precios.html', 'dist/contactanos.html', 'dist/Términosycondiciones.html'],
        options: {
            assetDir: ['dist', 'dist/css', 'dist/js'],
        }
    }
});

grunt.registerTask('css',['sass']);
grunt.registerTask('default', ['browserSync', 'watch']);
grunt.registerTask('img:compress', ['imagemin']);
grunt.registerTask('build', [
    'clean', 
    'copy',
    'imagemin',
    'UseminPrepare',
    'concat',
    'cssmin',
    'uglify',
    'filerev',
    'usemin',
])

};

Please somebody help me

The "P" in useminPrepare should be capitalized
