Contents returning as buffer

[dblodorn]

Hi im trying to use this to render templates in pug with gulp-wrap. for some reason when console out the contents of my test.md file get returned as a buffer 🤷‍♂️ ? Any idea as to why this would be happening - i'm using marked as the markdown renderer.

gulp.task('docs', function() {
  return gulp.src('./src/pages/*.md')
     .pipe(md(marked))
     .pipe(wrap(function(data) {
        console.log(data);
        var template = __dirname + '/src/pug/templates/' + data.contents.template;
        return fs.readFileSync(template).toString();
    }, {}, {
      engine: 'pug'
    }))
    .pipe(rename({extname:'.html'}))
    .pipe(gulp.dest('./dist/'));
});
