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)")) {":

ERROR: db_mongodb [mongodb_dbase.c:381]: db_mongodb_get_columns(): field [attribute] not found in result iterator

ERROR: db_mongodb [mongodb_dbase.c:739]: db_mongodb_store_result(): failed to set the columns

ERROR: db_mongodb [mongodb_dbase.c:918]: db_mongodb_query(): failed to store result

ERROR: db_mongodb [mongodb_dbase.c:927]: db_mongodb_query(): failed to do the query

ERROR: avpops [avpops_impl.c:381]: ops_dbload_avps(): db_load failed

I read on http://opensips-open-sip-server.1449251.n2.nabble.com/Connecting-to-mongodb-Replica-set-from-opensips-td7603254.html that "some modules are not safe to use with mongodb, namely ... avpops(do not recall the issue with this one) ... ". Does anyone know if this is correct / what the problem is? And should I then implement this myself using ndb_mongodb?

Thanks and regards,
