My Config file is like this

```
input {
	file {
     path => "D:\logstash\logstash-6.1.0\bin\repoprolog.log"
		start_position => "beginning"
		sincedb_path => "/dev/null"
		ignore_older => 0
		codec => multiline
		{
			pattern => "%{DATE}_%{TIME} - "
			negate => true
			what => "previous"
			auto_flush_interval => 1
	}}} filter {
	 grok {
match => {"message" => "%{DATE}_%{TIME} - %{POSINT:value} %{DATA:status} %{WORD:result} %{GREEDYDATA:final}"} }}output {
	elasticsearch { 
		hosts => ["localhost:9200"] 
	 }}

```

sample of my log file is:

```
2018-01-30_09:36:56.149 - 119263 [http-apr-8080-exec-8] INFO timeBased - validatepublisherLoggedinUser : DB Connection Established

```

I'm getting this error message:

I think this is some kind of configuration issue . Can someone help me how to solve this problem?
