this error happened after first time of receiving message from the rabbitmq

my logstash config is :::

input {
  	rabbitmq 
	{
		user => "user"
		password => "pass"
		exchange => "exch"
		queue => "queue"
		durable => true
		host => "ip addr"
		subscription_retry_interval_seconds => 5
		codec => "json"
	}
}


   output  
  {
    if [type] == "login" 
	{
		rabbitmq  
			{
				user => "user"
				password => "pass"
				exchange => "exch-out"
				exchange_type => "direct"
				durable => true
				key => "login-key"
				host => "ip addr"
				codec => "json"
			}
	}


 file {
              id => "All Input Data Logger"
              path => "/elas/log/rabbitmq_debug_events-%{+YYYY-MM-dd}"
              codec => rubydebug
      }
