"Unexpected reserved word..." error returned after gulp-haml build

[kaidez]

I'm trying to build out a .haml file using gulp-haml...test.haml builds test.html out to a html directory . After the build is done, test.html looks like this...

<pre class='error'>SyntaxError: Unexpected reserved word at Function.&lt;anonymous&gt;

My Gulp file looks like this:

var gulp = require('gulp');
var haml = require('gulp-haml');

gulp.task('build', function () {
  gulp.src('file.haml')
    .pipe(haml())
    .pipe(gulp.dest('./html'));
});

My haml file looks like this...

!!!5
%html{:lang => "en"}
 %head
  %meta{:charset => "UTF-8"}/
  %title Test
%body
  %div{:class => "container"}
    %header
    %main
    %footer 

Using... -gulp 3.8.8 -node 0.10.31 -Haml 3.1.7

I did a generic haml build outside of gulp to see if there were external issues outside of gulp or the plugin and the buld was OK...any help is appreciated. Thanks in advance.
