elasticsearch6.3 接收logstash 转发filebeat 的日志数据报错

elasticsearch.yml配置如下：

cluster.name: my-application

node.name: node-1

node.attr.rack: r1

path.data: /home/elasticsearch/data

path.logs: /home/elasticsearch/logs

network.host: 192.168.33.85

http.port: 9200

 
logstash配置如下：
 

input {

  beats {

    port => 5044

  }

}

filter {

  grok {

    match => { "message" => "%{COMBINEDAPACHELOG}" }

  }

  date {

    match => [ "timestamp" , "dd/MMM/yyyy:HH:mm:ss Z" ]

  }

}

output {

  elasticsearch { hosts => ["http://192.168.33.85:9200"] }

  stdout { codec => rubydebug }

}

 
Ps：如果上述hosts 地址后出现异常字符，实属网页乱码。hosts => ["http://192.168.33.85:9200"]  
filebeat配置如下：
 

filebeat.inputs:

- type: log

  enabled: true

  paths:

    - /var/log/*.log

filebeat.config.modules:

  path: ${path.config}/modules.d/*.yml

  reload.enabled: false

setup.template.settings:

  index.number_of_shards: 3

setup.kibana:

output.logstash:

  hosts: ["localhost:5044"]

logstash能成功接收filebeat的日志数据，elasticsearch 报错如下：

 
 
logstash 在设置输为input { stdin { } }时，elasticsearch 接收不会报错。目前尝试接收filebeat的日志后会出现上述问题，有哪位大牛知道问题所在?
 
Ps: 还未尝试filebeat 直接发送日志数据到elasticsearch
