Question

嗨我的调试工具栏有问题，当我尝试加载页面时（在localhost上）所有代码都正确加载但是在加载代码后出现了警告：

加载Web调试工具栏时出错（500：内部服务器错误）。你想打开探查器吗？

我可以选择：确定或取消。

当我点击取消时没有任何反应，但如果我点击确定我得到（http://127.0.0.1:8000/_profiler/ae356f）：

命名空间没有注册路径＆＃34; security＆＃34;。

{% block menu %}
        <span class="label {{ not collector.enabled or not collector.token ? 'disabled' }}">
            <span class="icon">{{ include('@security/Collector/icon.svg') }}</span>
            <strong>Security</strong>
        </span>
{% endblock %}

我可以分享Composer文件：

你们有什么想法可以解决这个问题的原因吗？我已经尝试了this解决方案但没有效果。请帮忙。

在法国网站openclassroom.fr，一个人有同样的错误500.我不知道真正的隐藏错误，但他的错误是

安全上下文不包含身份验证令牌。一种可能原因可能是没有为此URL配置防火墙。

问题似乎是测试令牌是否存在：

if(null == $this->securityContext->getToken() && HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType())
{
    return;
}
