title: PHP/Phalcon Error: Closed without sending a request; it was probably just an unused speculative preconnection
body: <p>I have a basic controller action:</p>
  
  <pre><code>    public function createAction() {
          $this-&gt;view-&gt;disable();
  
          $formData = $this-&gt;request-&gt;getJsonRawBody();
  
          $user = new Users();
  
          $user-&gt;first_name = $formData-&gt;first_name;
          $user-&gt;last_name = $formData-&gt;last_name;
          $user-&gt;email_address = $formData-&gt;email_address;
          $user-&gt;password = $formData-&gt;password;
  
          // this prints to my debug log.
          $result = $user-&gt;save(); 
          AppLogger::$logger-&gt;debug(print_r($result, true)); // this does not print.
          AppLogger::$logger-&gt;debug("oh boy #2"); // this does not print either.
          // which seems to tell me that the line above it is problematic,
          // but there is no error output from `phalcon serve`
  
          echo Json::encode($result);
      }
  </code></pre>
  
  <p>The closest thing I see to an error is this: <code>PHP/Phalcon Error: Closed without sending a request; it was probably just an unused speculative preconnection</code>. This is appearing in the output of <code>phalcon serve</code>.</p>
  
  <p>I'm running <code>phalcon serve</code> in VSCode on Windows.</p>
