We are trying to ship jira application logs via Fluent d. Need a multiline regex to parse

Below is the sample log we using :

Please find the below configuration using to parse

<source>
@type tail
@LOG_level debug
path /etc/td-agent/config.d/sample_log.log
pos_file /etc/td-agent/config.d/test.pos
format multiline
format_firstline /\d{4}-\d{1,2}-\d{1,2}/
format1 /^(?<time>\d{4}-\d{1,2}-\d{1,2} \d{1,2}:\d{1,2}:\d{1,2},\d{3})\s+(?<thread>.*)\s(?<level>(WARN|DEBUG|INFO|ERROR|FATAL))\s+(.*)?\s*\[(?<class>[^\s]*)\]\s+(?<message>.*)/
tag file.debug
</source>

<filter file.**>
@type record_transformer
<record>
__clp_index test
__clp_type aws_uat_application_jira
</record>
</filter>

## match tag=debug.** and dump to console
<match file.debug>
@type stdout
@idoutput_stdout
</match>

<match file.**>
@type forward
expire_dns_cache 300
dns_round_robin true
@LOG_level info

<server>
host fluentd.log-uat.factset.com

<buffer>

</buffer>
</match>

Facing errors in console any better multiline regex?
