Sample setting with elasticsearch input plugin doesn't work

[shin0higuchi (Shin Higuchi)]

A sample setting on https://www.elastic.co/guide/en/logstash/current/plugins-inputs-elasticsearch.html may not work.

• Sample
  input {
  elasticsearch {
  hosts => "es.production.mysite.org"
  index => "mydata-2018.09."
  query => ""
  size => 500
  scroll => "5m"
  docinfo => true
  }
  }

• Version: logstash 5.4.0

• Operating System: macOS Sierra 10.12.4

• Config File (if you have sensitive info, please remove it):

  input{
  elasticsearch{
  hosts => "localhost"
  index => "packetbeat-"
  user => "elastic"
  password => "changeme"
  query => ''
  }
  }
  filter{}
  output{
  file{
  path => "/Users/SHIN/Elastic/Elastic5.4/logstash-5.4.0/test.out"
  }
  }

• Error Message:
  Error: [500] {"error":{"root_cause":[{"type":"json_parse_exception","reason":"Unexpected character ('' (code 42)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@5d974f5e; line: 1, column: 2]"}],"type":"json_parse_exception","reason":"Unexpected character ('' (code 42)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@5d974f5e; line: 1, column: 2]"},"status":500}
