Hello, did you change the database structure? Because the crash seems to be because attrs field is NULL, but database schema should prevent it. Or, maybe you use a database backend that cannot enforce that, which one do you use (db_myql, ...)?

Hello, probably the module code needs also some updates, it is rather old and likely designed for db backends that enforce non-null values, like in the create statement:   * https://github.com/kamailio/kamailio/blob/master/utils/kamctl/mysql/dialpla… So it does not do much extra checks in the code, but these days there are other db connectors that may not have strict schema implementation like db_redis or db_mongodb. For now, I pushed a push a patch to jsonrpcs module to print 'null' value in jsonrpc response, when the value passed from other modules to it is C-NULL. This should prevent (hopefully) the crash from happening, even you revert back to have null value in database:   * https://github.com/kamailio/kamailio/commit/c48e409b741821fa470788b3bca0ead… I will have to check the ctl and xmlrpc modules to see what they do in similar cases, to cover also the use of kamcmd for the same situation.
