[SR-Users] error using avp_db_load with mongodb

[hdssdsdsdsfsdf hdssdsdsdsfsdf]

It seems I'm missing something when checking the structure. I've multiple entries in the database now that seem to have exactly the same types, but the config works for one, and gives an error on the other one:

{ "_id" : ObjectId("597b5698e498421a40458dc3"), "uuid" : "", "attribute" : "email", "value" : "sip:555 at bla.bla", "type" : 0, "username" : "555", "domain" : null }
{ "_id" : ObjectId("597b5d9a61d1521f067391ae"), "uuid" : "", "attribute" : "email", "value" : "sip:123 at bla.bla", "type" : 0, "username" : "666", "domain" : null }

I compared all the types, and they're the same, using statements like:

typeof db.usr_preferences.findOne({"username":"666"})._id

The first entry has been made by using:
     avp_db_delete("$to/username","$avp(s:email)");
     avp_printf("$avp(s:email)","$ruri");
     avp_db_store("$to/username","$avp(s:email)");
So, using kamailio. The second version has been created by me manually in the database (which is what I'll do for the real entries). 

The first entry now works fine, but the second one gives the following error:
ERROR: <core> [usr_avp.c:424]: search_avp(): 0 ID or NULL NAME AVP!
when using the initial code again:

                        if (avp_db_load("$to/username", "$avp(s:email)")) {
                                xlog("bla02");
                        }

Where does the second entry differ?
