Why is there an error when changing gulp.src in gulp-rigger?

Question

HTML

this is how it works

gulp.task('html', function(){
  return gulp.src('src/*.html')
    .pipe(rigger())
    .pipe(gulp.dest(path.build.html))
    .pipe(connect.reload());
});

but if I change the source path

gulp.task('html', function(){
  return gulp.src('src/oborudovanie/*.html')
    .pipe(rigger())
    .pipe(gulp.dest(path.build.html))
    .pipe(connect.reload());
});

throws an error

buffer.js:67
    throw new TypeError('must start with number, buffer, array or string');
          ^
TypeError: must start with number, buffer, array or string

Answer 1

Change permissions so that gulp can access the directory

Answer 2

Option 2:
1) Left permissions on the folder -))
2) An error occurs recursive calls, carefully look at your templates, file names and paths in them ...
For example, some included file is trying to include something else ...
