I've setup sentry, but I typo'd on the first page where it asked me to set the default domain that it would use. I can't seem to find that stored anywhere - it's not in config.yml or the database, that I can see.
Where is it stored?
I still don't know where that initial value is stored, but I managed to override it by setting in sentry.conf.py:
SENTRY_URL_PREFIX
and in config.yml:
system.url-prefix
(It looks like either works, but the second is the preferred format going forward?)
