Extraction from log

[aknotik]

Not sure is this an issue or not. I'm using OpnSense instead of pfSense and of course it was working with OpnSense as well. Since OPNsense 20.7.4-amd64 version, there is changes in log format. OpnSense team added log identifier and logs extraction doesn't work now.
This is how it was:
Nov 4 07:06:32 filterlog: 97,,,0,em0,match,pass,out,4,0x0,,63,30672,0,DF,17,udp,75,10=192.168.250.126,192.168.248.110,39612,161,55
And now it is: Nov 5 09:06:55 filterlog**[62051]**: 97,,,0,em0,match,pass,out,4,0x0,,63,30672,0,DF,17,udp,75,10=192.168.250.126,192.168.248.110,39612,161,55

Forced to add regex: EXTRACT-ipv4_tcp = filterlog**[(.])**:\s(?[^,]),(?<sub_rule>[^,]),(?[^,]),(?<tracker_id>[^,]),(?<dest_int>[^,]),(?[^,]),(?<vendor_action>[^,]),(?<vendor_direction>[^,]),(?<ip_version>4),(?[^,]),(?[^,]),(?[^,]),(?[^,]),(?[^,]),(?[^,]),(?<transport_id>[^,]),(?<vendor_transport>tcp),(?[^,]),(?<src_ip>[^,]),(?<dest_ip>[^,]),(?<src_port>[^,]),(?<dest_port>[^,]),(?<payload_bytes>[^,]),(?<vendor_tcp_flags>[^,]),(?<sequence_number>[^,]),(?[^,]),(?[^,]),(?[^,]),(?[^$])$

Thanks for your work! And please delete if post is not applicable.
