[SR-Users] lua_run seems to be working in asynchronous way

Hi there, I'm using kamailio version 4.2.2 to a short time, and I'm using lua scripts to build some avps with information needed to make calls(lua functions uses redis as source data to build avp data.), what i have noticed today making some tests is that when i make a call my lua function: if(!lua_run("get_prefs","$fU","$fd")) { xdbg("SCRIPT: failed to execute lua function!\n"); } kamailio gets the avp's after send the invite to the destine,(the invite will fail because kamailio needs avp information). it seems that kamailio calls the lua_run in asynchronous way, i never noticed that before in old version. is that a normal behavior or it is an issue in this version?
