title: Symfony4: Unable to find the controller for path "/api/login_check". The route is wrongly configured
body: <p>I am tyring to set up symfony4 api JSON login by JWT.
  The api platform core bundle is installed and I followed this instruction: <a href="https://api-platform.com/docs/core/jwt/" rel="noreferrer">https://api-platform.com/docs/core/jwt/</a></p>
  
  <p>I created the custom user provider as described.
  By opening the URL /api/login_check the error message "Unable to find the controller for path "/api/login_check". The route is wrongly configured." occurs.</p>
  
  <p>By sending a POST request I get the error page in html.</p>
  
  <p>This is my <strong>routes.yaml</strong>:</p>
  
  <pre><code>#index:
  #    path: /
  #    controller: App\Controller\DefaultController::index
  api_login_check:
      path: /api/login_check
  </code></pre>
  
  <p>And here is my <strong>security.yaml</strong>:</p>
