Grok - ConfigurationError", :message=>"Expected one of #, {, ,, ]

[MrFrost]

Hello,
I tried to figure out why I get below error but I do not see what could be wrong in my logstash config file. Hopefully someone can help. I did check message patter in "Grok Debugger" and it works there. Any ideas why it does not run?

Example input data:

1520428168091,513,Request,200,OK,test 1-4,text,true,,1037,376,20,20,513,0,442

Logstash pipeline config file:

input {
    tcp {
		port => 5000
	}
    file {
                path => ["/usr/share/logstash/pipeline/reports/*.csv"]
    }
}

filter {
    grok {
        match => { "message" => "(%{NUMBER:timestamp})?,(%{NUMBER:elapsed})?,(?<label>[^,;]+)?,(%{INT:responseCode})?,(%{WORD:responseMessage})?,(?<threadName>[^,;]+)?,(%{WORD:dataType})?,(%{WORD:result})?,(?<failureMessage>[^,;]+)?,(%{NUMBER:bytes})?,(%{NUMBER:sentBytes})?,(%{NUMBER:grpThreads})?,(%{NUMBER:allThreads})?,(%{NUMBER:latency})?,(%{NUMBER:idleTime})?,(%{NUMBER:connect})?"}
    }

}
output {
elasticsearch {
hosts => "elasticsearch:9200"
user => myuser
password => mypass
index => "logstash-jmeter-%{+YYYY.MM.dd}"
}
}

Error in console:
