logstash keeps restarting with the following error when using varnishlog (logstash-input-varnishlog) with the following configuration. Any idea how to get it to work?

input {

varnishlog {}

}

output {  
elasticsearch { hosts =\> ["localhost:9200"] }  
}

I am using  
logstash 5.0.1  
varnish-4.1.3
