[SR-Users] db_mongodb get columns error

Hi, After restarting Kamailio, I got the following errors during the startup: kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:381]: db_mongodb_get_columns(): field [caller_sock] not found in result iterator kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:739]: db_mongodb_store_result(): failed to set the columns kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:918]: db_mongodb_query(): failed to store result kamailio[12614]: ERROR: db_mongodb [mongodb_dbase.c:927]: db_mongodb_query(): failed to do the query kamailio[12614]: ERROR: dialog [dlg_db_handler.c:257]: select_entire_dialog_table(): Error while querying database What may be causing the issue? I should always have a caller_sock in every dialog document. Thanks, Mickael
