所以我的公司让我将我们存储库的 Logstash 版本从 6.6.2 升级到 7.13.3。
在修复升级过程中的其他一些错误后，最后一步似乎是更改配置文件中的 ruby 语法。
但是，我对这门语言不太熟悉，不知道为什么语法不再有效。
这是我们从文件中得到的语法错误之一的示例。

}
此错误引用的行：
grok {
match => { "message_string" => "(?<ucd_environment_name1>(?<=release_ucd_environment_name:)[\w-.]*)" }
}
还有其他几行发生了此错误，但它们都具有与此行相似的语法，因此我确信我也可以对这些行应用相同的更改。
如果有人能指出我如何更改此行以检查此 Logstash 版本在语法上接受的相同表达式。
