无法将弹性搜索从5升级到6

Question

我试图运行升级助手以便将ElasticSearch从5升级到6，但是我遇到了以下错误：

Deprecated script security settings changes
This issue must be resolved to upgrade. Read Documentation
Details: [node[instance-0000000093] used these script-security settings:[script.inline, script.stored, script.file, script.engine.painless.stored, script.engine.painless.file, script.engine.expression.stored, script.engine.expression.file, script.engine.mustache.inline, script.engine.mustache.stored, script.engine.mustache.file]]

我已经查看了设置和我们的Kibana配置，找不到任何正在使用的脚本的引用。

是否还有其他人遇到类似问题，您如何解决？

谢谢。
