Thanks for the response!
Try send_error() instead. If it works, it’s more sensible anyway.
It doesn't appear to work. Same error as 'pass' and 'forward'. It seems
maybe send_error() is not allowed within a before_hook.
You should be caching database connections. Re-opening it on each and
every hit is a bit expensive, even for a localhost connection.
Hmmm does this code not do that? I'm using the Dancer Database plugin (and
not the old plain DBI), just setting the database dynamically (based on
$client) instead of from the typical ./config.yml. I assumed each database
would be cached automatically by the plugin.
Why 404?
Because the routes are named
/:client
/:client/foo
/:client/bar
/:client/foo/bar/foobar
etc...
so, if a database for /:client doesn't exist, it means (within the context
of my app) the URI doesn't exist.

Two lines replaces all that:

eval {

I’d like Dancer to gracefully fall through to a 404 error
Why 404? That means the URI names a nonexistent resource, which is more
appropriate for something like SELECT … = 0 records. This feels more like a
500 error.
Unless, that is, “missing customer DB” is something you expect your users to
run into.
I’ve tried “pass” and “forward”, but I receive a cryptic “Internal Server
Error” which I assume is because these keywords are not valid within
hooks, but I’m not sure.
Try send_error() instead. If it works, it’s more sensible anyway.
