无法从 kibana 查询指标数据？

如何解决无法从 kibana 查询指标数据？

我部署了 kibana 和 metricbeat，以便观察我在 AWS 中运行的应用程序的指标。我已根据此文档设置了 metricbeat：https://www.elastic.co/guide/en/beats/metricbeat/7.x/metricbeat-installation-configuration.html。

但是当我打开 kibana 并单击 metric 时，它显示此错误：

我在 kibana 日志中看到以下错误消息。但是我该怎么做才能修复它。我找不到有关该错误的任何其他信息。
