Ruby on rails 神秘的类型错误：没有为OpenSSL:：Digest类定义_dump_数据

我们最近看到这个错误越来越多地出现，但并不一致，也无法手动重现。

我们在Ruby2.6.5上有一个标准的RubyonRails应用程序（5.2.3）

我读过所有其他类似标题的帖子，但我不知道这是从哪里来的，这里是我们的stacktrace：

有时错误率高达该端点请求的13%，但通常要低得多，有时根本不会发生：

另一个谜团是为什么它主要发生在我们的一个地区。我们部署到多个AWS区域，美国是我们最大的区域，但只生成现在说确定可能有点为时过早，但我们可能通过从

config/initializers/i18n.rb中删除以下两行来解决它

I18n::Backend::Simple.send(:include, I18n::Backend::Cache)
I18n.cache_store = ActiveSupport::Cache.lookup_store(:memory_store)

在部署此更改之前的两周内，错误已从每天最多1k个错误降至一位数或两位数

部署之后，我们已经两天没有看到一个了

我不确定删除缓存是否会对性能产生任何影响，但我注意到我们的其他rails应用程序没有这种功能。
这是缓存的一般错误
在缓存实现中，大多数情况下都会发生
未定义任何转储数据
和
未定义封送转储等错误
，很难知道错误发生的位置

为了修复这个gerenic错误，我建议调查所有新的
GEMs/features/edits
，因为在某些情况下，实现没有在“缓存数据”中获取常规数据

例如，在我的实际实现中，当尝试将
searchkick
与
view\u components\u reflections
（谁可以缓存所有数据）一起使用时，会出现此错误。我需要调整如何发送数据以查看组件，以使其能够正常工作。
能否发布完整的堆栈跟踪，您缺少所有重要信息。感谢这可能与缓存和翻译有关。但不知道是什么，希望完整的追踪能提供线索clue@jamesc谢谢你看！是的，缓存和翻译可能会涉及其中——我只是不知道
OpenSSL:：Digest
是如何发挥作用的。可能是因为多部分请求负载中的文件？我们没有手动缓存任何内容。我认为这些翻译只适用于一些基本的状态验证，即完整堆栈跟踪之后的状态验证please@jamesc我用完整的堆栈跟踪更新了问题-这是我从Airbrake获得的所有信息。你认为有什么东西丢失了？6个月后，错误没有再次发生Hanks Jonatas，我想知道是不是一些宝石升级导致了我们的情况。但是，我们提供的解决方案（删除一些自定义缓存设置）为我们解决了这一问题：）
