Problem in gulpfile.js in index.html, how to fix?

Question

gulp.js

An error comes out:

[12:06:56] Task './*.html' is not in your gulpfile
[12:06:56] Please check the documentation for proper gulpfile formatting

Here is my gulpfile.js file

var gulp        = require('gulp'),
    neat        = require('node-neat').includePaths,
    sass        = require('gulp-sass'),
    browserSync = require('browser-sync'),
    sassFiles   = 'sass/**/*.scss',
    cssDest     = 'css/';

gulp.task('sass', function () {
    return gulp.src(sassFiles)
    .pipe(sass().on('error', sass.logError))
        .pipe(gulp.dest(cssDest));
});

gulp.task('browserSync', function(){
    browserSync.init(["./*.html", "css/*.css", "js/*.js"], {
        server: {
            baseDir: "./"
        }
    });
});

gulp.task('watch',['sass', 'browserSync'], function () {
    gulp.watch(sassFiles, ['./*.html'], ['sass']);
});

gulp.task('default', ['sass', 'browserSync', 'watch']);

I think the problem is in specifying the path ./*.html.
In the folder, the files are located like this, all on the same level:

-css    -> style.css
-sass  -> style.scss
-node_modules
-gulpfile.js
-index.html
-package.json

Answer 1

similar to "css/*.css" it looks like the first two characters are extra in "./*.html" if you specify baseDir: "./"
test different variations
these strings can also be placed in variables like sassFiles

Answer 2

Here in this line you are telling to execute the ./*.html task while watching sassFiles

Answer 3

Hey.
You have already been written, instead of the usual path, you declared the line as a task, which you do not have at all.
Try instead

gulp.task('watch',['sass', 'browserSync'], function () {
    gulp.watch(sassFiles, ['./*.html'], ['sass']);
});

Write

gulp.task('watch',['sass', 'browserSync'], function () {
    gulp.watch(sassFiles, './*.html', ['sass']);
});

(Square brackets removed)
Better yet, rewrite it like this:

gulp.task('watch',['sass', 'browserSync'], function () {
    gulp.watch(sassFiles, ['sass']);
    gulp.watch('./*.html', browserSync.reload);
});

Just think. sassFiles is the same line. She has no sq. brackets, and the second path to html files for some reason is already in square brackets.
