The backtrace is missing.
Why?

If it helps, here is a summary of php.ini:

log_errors = On
error_log = /var/log/error.log
display_errors = Off

You never told it to generate a backtrace.

But this is for manually generating.
Yet it seems to me that before (perhaps with an older version of php)
the backtrace was logged normally.

AFAIK PHP never did this, but xdebug does so - perhaps you had it
installed in earlier days.

I have found that with exceptions it works

$ php -r "trigger_error(123);throw new Exception;"
$ tail -n5 /var/log/error.log
[23-Apr-2022 15:30:31 Europe/Berlin] PHP Notice: 123 in Command line
code on line 1
[23-Apr-2022 15:30:31 Europe/Berlin] PHP Fatal error: Uncaught
Exception in Command line code:1
Stack trace:
#0 {main}
thrown in Command line code on line 1
