Confused with gulp-svg, how to set it up?

Question

gulp.js

I take files from img svg during processing, they end up in img sprite

gulp:

gulp.task('svg', function () {
    gulp.src('built/img/svg/menu/*.svg')
        .pipe(plumber())
        .pipe(svgMin())
        .pipe(svgSprite({
            "shape": {
                "spacing": {
                    "padding": 5,
                },
            },
            "mode": {
                "css": {
                    "dest": '.',
                    "layout": "diagonal",
                    "sprite": 'sprite.svg', 
                    "bust": false,
                    "prefix" : '$',
                    "dimensions": true,
                    "render": {
                        "styl": {
                            "dest": 'sprite-svg.styl',
                        }
                    }
                }
            }
        }))
        .pipe(plumber.stop())
        .pipe(gulpIf('*.styl', gulp.dest(assets/stylus), gulp.dest(assets/img/sprite)));
});

An error is displayed in the console, css searches and does not find, it turns out that the paths do not match, since the finished css is in built and is looking for 'css' in the same subfolder, how to make it so that there is one valid path?
