title: Symfony 5.x - An error occurred while loading the web debug toolbar
body: <p>I'm working with Symfony 5.X, it's a fresh install on docker with the image "bitnami/symfony".
  I use too "bitnami/nginx" and "bitnami/php-fpm". All work good except the web profiler toolbar.</p>
  
  <p>I passed the 2 last days on Google searching for a solution but nothing work.
  I can access the url <em>/_profiler/</em> but if I click on a token to view some details I get an error 500.</p>
  
  <pre><code>TypeError:

  <p>I read on forums that some people fix this problem with the package symfony/apache-pack but I don't want to use Apache because I have already Nginx.</p>
  
  <p>I have no more idea, I have tried so much things, if someone can help me it will be nice.</p>
