Custom log format with newlines not detected?

STR

I have this log (also with more entries) that is a multi-line log:

[2023-10-06 09:44:53 Debug]
Response:
Direction: Incoming
Request-Id: 16b34bdd-bla-bla
Status code: 500

There are more entries like this (or you can just duplicate this one), so #110 (comment) should not be the cause here.

Format

• message format: ^\[(.* .*) (.*)\]\n(.*) https://regex101.com/r/0l8fz7/1
  • also tried ^\[(.* .*) (.*)(\]) in case it must match all on the first line, but did not work either
• message start pattern: ^\[ https://regex101.com/r/vpzoZX/1

Also verified the RegEx via built-in search:

What happens

When opening the *.log file it always shows the log as not recognized.

What should happen

Recognize log

https://github.com/JetBrains/ideolog/wiki/Custom-Log-Formats suggests at several places that newlines are supported:

This pattern is applied only to visible log lines, so it may be somewhat bulky and slow. In this pattern, '.' also matches newline by default. This is done for ease of matching multi-line messages.

Thanks for your great research and analysis! I too can observe the same behavior on RubyMine 2023.2.5, Ideolog 222.1.0.0

My approach was to color all contiguous lines of an error message in a Rails log file. I tested and tried the corresponding regex here: https://regexr.com/7n2ct
