Why is the function being called multiple times?

Question

JavaScript

Hello!
Can you please tell me what is wrong with this function? Why is it giving an error when executing that the function is executed several times?

module.exports = function () {
    $.gulp.task('img:build', () => {
        return $.gulp.src(imgPATH.input)
            .pipe(cache(imagemin([
                imagemin.gifsicle({interlaced: true}),
                imagemin.jpegtran({progressive: true}),
                imageminJpegRecompress({
                    loops: 5,
                    min: 70,
                    max: 75,
                    quality: 'medium'
                }),
                imagemin.svgo(),
                imagemin.optipng({optimizationLevel: 3}),
                pngquant({quality: '65-70', speed: 5})
            ], {
                verbose: true
            })))
            .pipe($.gulp.dest(imgPATH.output));
    });
};

Got it!
For those who are interested, the working function looks like this:

$.gulp.task('img:build', () => {
        return $.gulp.src(imgPATH.input)
            .pipe(imagemin([
                imagemin.gifsicle({interlaced: true}),
                imageminJpegRecompress({
                    loops:4,
                    min: 70,
                    max: 75,
                    quality:'medium'
                }),
                imagemin.optipng(),
                imagemin.svgo(),
                imagemin.optipng({optimizationLevel: 3}),
                pngquant({quality: [0.65, 0.7], speed: 5})
            ], {
                verbose: true
            }))
            .pipe($.gulp.dest(imgPATH.output));
    });
