It seems that the modifier/lua-backend does not yet support flexible config krakend.

Hello, I would like to ask how to make this extra config readable in the flexible config krakend?

backend-a.json (flexible config): 
        {
            "endpoint": "/using-lua",
            "output_encoding": "no-op",
            "backend": [
                {
                    "url_pattern": "/v1/3aecd459-27d2-45bc-9026-235fed9c41c0",
                    "host": ["https://mocki.io"],
                    "method": "GET",
                    "is_collection": true,
                    "encoding": "json",
                    "extra_config": {
                        "modifier/lua-backend": {
                            "sources": ["./lua/count.lua"],
                            "post": "count(response.load())",
                            "allow_open_libs": true
                        }
                    }
                }
            ],
            "extra_config": {
                "qos/ratelimit/router": {
                    "max_rate": 1,
                    "client_max_rate": 1,
                    "strategy": "ip",
                    "capacity": 1,
                    "every": "1s",
                    "client_capacity": -3
                }
            }
        },

krakend.json (output): 
{
        "endpoint": "/using-lua",
        "output_encoding": "no-op",
        "backend": [
            {
                "host": ["https://mocki.io"],
                "url_pattern": "/v1/3aecd459-27d2-45bc-9026-235fed9c41c0",
                "encoding": "json"
            }
        ]
    },

Thank you.

Hi Fikih,

I'm not able to reproduce your problem with the provided info: the output is correctly including the Lua config

Can you share more info about how are you arranging your config files and the command you're spawning to generate the output?
