我观察到一些关于清除scroll id上下文的警告，在哪里检查可能的问题？
这些错误经常在日志中产生。
我想知道这是否是一个真实的问题，或者这需要被遗忘，但很难阅读日志与这样的“垃圾邮件”

首先，这些不是错误，而是警告。
您正在尝试清除滚动上下文（这是一个很好的实践！），但从您得到的响应来看，
字符串
原因是因为上下文不再存在，因此您的JSON请求得到404，客户端将其解释为错误情况。因此它试图解析JSON响应并找到
error字段，但没有任何字段，因为它本身不是错误。型
该异常被抑制并 Package 在
ElasticsearchStatusException中，您可以捕获和忽略该异常。此外，7.16中的RestHighLevelClient has been deprecated，因此您应该迁移到新的Java API Client。
