Call to undefined method error when twig debug mode is enabled

The error occurs where the debug button is rendered:

        $context['graphql_debug'] = [
          '#markup' => sprintf(
            '<div class="graphql-twig-debug-child"><div class="%s" data-graphql-query="%s" data-graphql-variables="%s" data-graphql-server="%s"></div></div>',
            'graphql-twig-debug-wrapper',
            htmlspecialchars($query),
            htmlspecialchars(json_encode($arguments)),
            $this->env->getGraphQlServer()->id()
          ),
        ];

Since the method getGraphQlServer() does not exist in graphql_twig 3.x (but in graphql_twig 4.x does) I reverted the changes and implemented it like it was in 3.0.0-beta1 and set the from url fix to /graphql/explorer

 $form = $('<form method="post" target="_blank"></form>').attr('action', Drupal.url('graphql/explorer')).appendTo(this),

Thanks for opening the merge request. With that patch applied, I still get the following error:

Error: Cannot access protected property GraphQL\Error\Error::$message in __TwigTemplate_511eccd1dbfb90f954c68860ff9ce526->display() (line 121 of modules/contrib/graphql_twig/src/GraphQLTemplateTrait.php).

I re-rolled the patch with an additional fix for this error.
