Nothing is getting indexed

Elastic Stack Logstash
4

Right now I have another issue:

My log file is of the pattern:

Job STARTED at 2014/02/19 19:03:48 (jobId=20140216_190624_s2aZn, jobExecutionId=20140219190348_rmzXR)

for this my filter looks like this:

filter
{
grok {

    	match => {"message" => "[\n]### Job STARTED at %{GREEDYDATA} (jobId=%{GREEDYDATA:jobid}[\n]"}
	}

date {
match => ["event_timestamp", "yyyy/MM/dd HH:mm:ss"]
}

}

When i run the logstash, i get the below error:
'end pattern with unmatched parentheses'

Need some help around it real quick,
