[SR-Users] Lua script reload

Hi! I’m playing with new KEMI framework and trying to reload script without reloading Kamailio. Lua code is mostly one from example. ... modparam("app_lua", "load", "/etc/kamailio/lua/kamailio.lua") cfgengine "lua" ... So, I’m changing lua code and giving command kamctl rpc app_lua.reload But in the answer {   "jsonrpc":  "2.0",   "error":  {     "code": -32000,     "message":  "Execution Error"   },   "id": 11098 } In syslog there is a string /usr/sbin/kamailio[10939]: ERROR: app_lua [app_lua_api.c:399]: lua_sr_reload_script(): reload is not activated What is need to be done to activate reload?
