SyntaxWarning: invalid escape sequence '\\-'

Since I upgraded to v49, I get this in Apache's error log:

==> /var/log/apache2/error.log <==
[Tue Jun 24 11:05:09.871512 2025] [wsgi:error] [pid 44401:tid 135269508437696] /usr/lib/sheltermanager3/web062/debugerror.py:31: SyntaxWarning: invalid escape sequence '\\-'

But I cannot reproduce it, and it's very low occurrence:

grep djangoerror_t /var/log/apache2/error.log |ccze

I don't know what to look for in asm3.conf.

It's part of an issue with the webpy library and Python 3.10+. We fixed this and other issues after 49 was released by writing our own error handler to replace webpy's debugerror.py

Since it's only a warning, it should not be interfering with the running of the application and you should be safe to ignore it.
