Magento2.4.5 会话缓存限制器在标头已发送后无法发送

问题描述 投票：0回答：1

我经常在我的 Sentry 报告中看到以下问题：

在发送标头后，无法发送会话缓存限制器。

这是在调用 

session_start()
函数之前输出某些内容时抛出的错误。但我想不出有什么可以做到这一点。

我们的设置是在 php8.1 上使用 Varnish 缓存设置 nginx / php-fpm。

有人有想法吗？

谢谢！

只通过代码找到了

echo
或类似的东西，但没有找到任何东西。

你找到这个问题的答案了吗？我在 Magento 2.4.6-p2 中面临类似的问题，但我无法真正找出它的来源。
