I implemented call forwarding according to https://www.kamailio.org/wiki/tutorials/mini-howto-admin/call_forwarding, which is working fine. When I replace db_mysql with db_mongodb however, I receive an error on "if (avp_db_load("$ruri/username", "$avp(s:fwd_blind)")) {":

can you set debug=3 in kamailio.cfg, restart kamailio and test again? Then grab the log messages from syslog and send them here. It should provide more debug information.

Is there a record for this query? Or should be an empty response (no record returned)?
