lua_dostring("sr.pv.seti("$$var(var1)", $avp(var1) < $avp(var3) and 1 or 0)");
results in error : kamailio app lual_dostring(): error from Lua: attempt to index global 'sr' (a nil value)
replacing sr with KSR is working :
lua_dostring("KSR.pv.seti("$$var(var1)", $avp(var1) < $avp(var3) and 1 or 0)");
Shall we update the docs for https://kamailio.org/docs/modules/devel/modules/app_lua.html#app_lua.f.lua_d... ?
