Singular glob in an array of globs throws file not found error

See original GitHub issue

When using Gulp v4 (using vinyl-fs@2.4.4) and a singular glob in an array of globs doesn’t match a file, the task fails with an error. The same glob configuration doesn’t fail in Gulp v3. For example if foo.map exists but b.json doesn’t, this task:

gulp.task('angry', function testTask() {
  return gulp.src(['*.map', 'b.json'])
    .pipe(gulp.dest('./output'));
});

will output:

[12:01:43] Using gulpfile ~/Documents/glob-bug/gulpfile.js
[12:01:43] Starting 'angry'...
[12:01:43] 'angry' errored after 45 ms

The full reproduction of the issue is in this gist: https://gist.github.com/vdh/89958706d508dfda9b3c8cca8f46feb4

The gist also includes glob-stream.js for reproducing the bug without gulp or vinyl-fs.

@vdh thanks, perfect. I’ll dig into this when I have some free time.

Everything is undocumented because we haven’t shipped. You can build a glob with your singular file included and it will also solve your problem.
