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 https://github.com/JetBrains/ideolog/issues/110#issuecomment-847054388 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: grafik

What happens

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

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.
