目前我在 Google App Engine Flex 环境中使用 Symfony 4。
我正在尝试在我的日志条目中添加额外的“标签”以帮助调试，我一直在使用 Stackdriver 处理程序来记录事件，并且我尝试将新标签添加到在本地可以正常工作的 Stackdriver 处理程序，但不能当我部署到 GAE 时工作。
我的主要目标是为所有日志条目添加一个标识符，以帮助通过执行对条目进行分组。
有人能告诉我为什么我的 Stackdriver 处理程序中的标签没有传递到日志吗？
GAE 实例中的日志条目只有如下标签：
labels: {
appengine.googleapis.com/trace_id: "58a54e17ef1110b2720f0b103033187d"
}
