title: Simple POST using Lumen
body: <p>I have in routes.php the following method:</p>
  
  <pre><code>$app-&gt;post('insertGender', function ($NAME) {
          $result = DB::insert("INSERT INTO HK_GENDER (NAME) VALUES (?)",[$NAME]);
          return ($result)? "wow":"Noo";
      });
  </code></pre>
  
  <p>I try to pass the parameter via form using Postman
  <a href="https://i.stack.imgur.com/g3fcr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/g3fcr.png" alt="enter image description here"></a>
  and I get an error </p>
  
  <pre><code>Missing argument 1 for Closure::{closure}()
  in routes.php line 93
  at Application-&gt;Laravel\Lumen\Concerns\{closure}('2', 'Missing argument 1 for Closure::{closure}()', '93', array()) in routes.php
  at Closure-&gt;{closure}()
  </code></pre>
  
  <p>Why is the parameter provided not used?</p>
