gulp.task("f1", () => {
    gulp.src([], {"allowEmpty": true})
    .pipe(gulp.dest(location));
})

Error: Invalid glob argument: is thrown for the above snippet

gulp.task("f1", () => {
    gulp.src("[]", {"allowEmpty": true})
    .pipe(gulp.dest(location));
})

whereas, it is working fine. Is this the expected behaviour ? Anyway to use allowEmpty for empty array ?
Anyhow the issue can be solved by skipping the task for empty array, just wondering is there any proper way to use allowEmpty for empty array.
Any suggestion would be helpful. Thanks in advance
