Can't set nil for property of table

[Alex009]

for example i have response:

{
            "id": "123",
            "field": "dsdsd"
}

and i want to set null for field in some cases. When i try do it:

item:set("field", nil)

i not have errors, but also result not changed - i still got dsdsd

you should use the nil helper https://github.com/krakend/krakend-lua/blob/master/types.go#L7-L13

item:set("field", luaNil.new())
