Lua cluster must be configured in Envoy filter.. but it is configured

Networking

Hi.
I’ve spend a lot of time to understand what’s wrong with my config.
I’ve even tried a config from istio documentation and it’s always says “lua cluster invalid. must be configured.”

Can someone please help to understand what am I missing?
Thanks!

Attaching my config:
