Just been trying to integrate Opensips with Freeswitch by following this old guide:

I think I have managed to get the other stuff working alright. However, it seems that the user extensions aren't being pulled from the opensips database. When I run:

 list_users group default

I get the following error:

2021-05-25 02:57:32.297372 [ERR] mod_lua.cpp:202 /usr/share/freeswitch/scripts/xml_handler.lua:40: attempt to index global 'params' (a nil value)
stack traceback:
        /usr/share/freeswitch/scripts/xml_handler.lua:40: in main chunk
2021-05-25 02:57:32.297372 [ERR] mod_lua.cpp:270 LUA script parse/execute error!

I am using Opensips 3.0 on Amazon EC2. Any help would be appreciated.

Best wishes.
