准备从从客户端上使用filebeat收集日志汇总到logstash，之前10台机器都没有问题，但是之后遇到一个比较棘手的报错信息，我试图在网上搜寻一些线索，但是并没有什么进展，老师能不能帮忙看一下什么原因？
报错信息如下：

我的filebeat.yml文件内容是这样的：
filebeat.inputs:

• type: log
  enabled: true
  paths: /work/logs/cecsh_access.log
  tags: [“hlwb-shrx-cecsh-10.10.4.149”]
  fields_under_root: true
  output.logstash:
  hosts: [“10.10.9.10:5046”]

  由于之前10台filebeat配置文件都是按照这个格式去编写，并且他们也都是成功上传日志的状态，我不认为这个是配置文件错误导致的启动失败，但是又找不到相应的故障案例可以参考，麻烦老师看一下，您有遇到过诸如此类的报错吗？
