Gulp task doesn't quit using ctrl-c

[paulmist]

What were you expecting to happen?

After running a gulp task (gulp serve) and then pressing ctrl-c, I expected the task to end.

What actually happened?

The task keeps running in the background.

Please give us a sample of your gulpfile

"use strict";

const gulp       = require('gulp'),
	browsersync  = require('browser-sync').create(),
	sass         = require('gulp-sass'),
	notify       = require('gulp-notify'),
	cssnano		 = require('gulp-cssnano');

const supported = [
	"defaults"
];

// BrowserSync
function browserSync(done) {
	browsersync.init({		
		/*
		server: {
			baseDir: ".",
		},
		*/
		host: 'https://localhost:8443',
		proxy: 'https://localhost:8443',
		port: 3000,
		open: false

	});
	done();
}

// BrowserSync Reload
function browserSyncReload(done) {
  browsersync.reload();
  done();
}

//Watch
function watchFiles(){
	gulp.watch("borrow-style.scss", scss);
	gulp.watch("./scss/*.scss", scss);
	gulp.watch("./client/scss/*.scss", scss);
	gulp.watch("./js/*.js").on('change', browsersync.reload);
	gulp.watch("./*.php").on('change', browsersync.reload);
	gulp.watch("./anotherstyle.css").on('change', browsersync.reload);
	gulp.watch("./style.css").on('change', browsersync.reload);
	gulp.watch("./template-parts/*.php").on('change', browsersync.reload);
}

function scss(){
	return gulp
	.src("borrow-style.scss")
	.pipe(sass({
		outputStyle: 'compressed'
	}).on('error', sass.logError))
	.pipe(cssnano({
		zindex: false,
		autoprefixer: {browsers: supported, add: true}
	}))
	.pipe(gulp.dest("."))
	.pipe(notify("Compiled: <%= file.relative %>"))
	.pipe(browsersync.stream());
}

const serve = gulp.parallel(watchFiles, browserSync);

exports.serve = serve;

Terminal output / screenshots

If I run ps I can see:

 PID TTY           TIME CMD
  777 ttys000    0:00.73 -zsh
 3229 ttys000    0:03.31 gulp serve

Please provide the following information:

• OS & version: MacOS Sonoma 14.4
• node version (run node -v):v14.17.1
• npm version (run npm -v):9.7.1
• gulp version (run gulp -v):4.0.2

This issue tracker is not for help with external modules.

I'm sorry - I don't follow?

My issue is with Gulp tasks not stopping - not module.

Can you point me in the right direction instead of a total dead end?

[phated]

I cannot because this is not a support forum.
