title: (NodeJs, Express) including an EJS file with only functions results in error
body: <p>I am currently setting up a shop with Node, and there are a lot of helper functions that I will re-use across different template files (such things as calc_taxes() ... ) For some odd reason, when I try to include a template partial that contains only functions, I get an error in the console. </p>
  
  <p>(i'm using this syntax)</p>
  
  <pre><code>&lt;%- include functions.ejs %&gt;
  </code></pre>
  
  <p><strong>the error I'm getting</strong></p>
  
  <pre><code>express deprecated res.send(body, status): Use res.status(status).send(body) instead routes/errors.js:11:7
  </code></pre>
  
  <p><strong>example code</strong></p>
  
  <pre><code> &lt;% products.forEach(function(product){ %&gt;
  
          &lt;div class="item" dkit-grid="col-3"&gt;
              &lt;div class="item_img" dkit-grid="col-12"&gt;
                  &lt;img src="&lt;%= get_product_image( product ) %&gt;"&gt;
              &lt;/div&gt;
  
              &lt;div class="item_desc" dkit-grid="col-12"&gt;
                  &lt;a href="/produit/&lt;%= get_product_slug( product ) %&gt;" class="item_name"&gt; 
                      &lt;%= get_product_name( product ) %&gt; 
                  &lt;/a&gt;
                  &lt;span class="item_price"&gt; 
                      &lt;%= get_product_price( product ) %&gt; 
                  &lt;/span&gt;
              &lt;/div&gt;
          &lt;/div&gt;
  
      &lt;% }); %&gt;
  </code></pre>
  
  <p>I have tested with a file containing dummy content like an <code>&lt;h1&gt;wowow&lt;/h1&gt;</code> and it outputted... But with my file containing only a bunch of function declaration I get nothing :(.</p>
