Regexp test in Fluentular passed but pattern not matched when use Fluentd to get logs

[huy96cpqnvn]

When I test regexp in Fluentular, response is in the form of json This is my regexp:

/^((?<time>([0-9]{4})-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1]) [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2},[0-9]{3})\s)(?<level>[^ ]*)\s+(?<package>[^ ]*)\s+\[(?<thread>[^\]]*)\]\s+(?<message>(.|\s)+)$/m

This is regexp and string (Logs of Java Spring boot include Exception) enter image description here

This is response in Fluentular: enter image description here

But when I use Fluentd with td-agent.conf:

<source>
  @type tail
  path /home/huy/Documents/jbsv-logs/event.log
  pos_file /home/huy/Documents/jbsv-logs/event.log.pos
  tag log.log
  <parse>
    @type regexp
    expression /^((?<time>([0-9]{4})-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1]) [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2},[0-9]{3})\s)(?<level>[^ ]*)\s+(?<package>[^ ]*)\s+\[(?<thread>[^\]]*)\]\s+(?<message>(.|\s)+)$/m
  </parse>
</source>

<match *.**>
  @type stdout
</match>

I can get response type json for first line include timestamp, level,..that i defined. But from the 2nd line, after Enter, logs display: fluent.warn: {"message":"pattern not matched: "...}

Logs in td-agent.log:

I want to key "message" includes all of Exception line.

Please help me this problem. Thanks a lot!
