[LogStash::Runner] runner - Logstash shut down

[travlest]

I am trying to configure http_poller for logstash. But I've encountered this error.

location : /etc/logstash/conf.d/logstash_http_poller
input {
http_poller {

•    urls => {*
  

•            urlname => "https://randomuser.me/api"*
  

•    }*
  

headers => { Accept => "application/json" }

•    request_timeout => 60*
  

•    schedule => {every => "20s"}*
  

•    codec => "line"*
  

•    metadata_target => "http_poller_metadata"*
  

}
}

output{
elasticsearch {

•    hosts => ["http://localhost:9200"]*
  

•    index = "logstash_http_poller"*
  

}
stdout {codec => rubydebug}
}

Error.

Can anyone help me with this?
