Hi everyone,

I'm using ELK 7.13 and I have a question about the translate filter plugin.

I have the following dictionary.json

```auto
{
	"TUTU": {"identifiant": "TRANSLATE VALUE FOR TUTU"},
	"TOTO": {"identifiant": "TRANSLATE VALUE FOR TOTO"}
}

```

I'm trying to enrich the following field

```auto
"field_to_enrich" => [
        [0] "123",
        [1] "TUTU"
]

```

My translate part is

```auto
translate {
	field => "[field_to_enrich]"
	iterate_on => "[field_to_enrich]"
	destination => "[field_to_enrich]" 
	dictionary_path => "PATH_TO_DICT.json"
	exact => true
	override => true
	fallback => "%{[field_to_enrich]}"
}

```

I'm expecting the following result

```auto
"field_to_enrich" => [
        [0] "123",
        [1] "TRANSLATE VALUE FOR TUTU"
]

```

But I'm getting

```auto
"field_to_enrich" => [
        [0] "123,TUTU",
        [1] {
            "identifiant" => "TRANSLATE VALUE FOR TUTU"}
]

```

My question is about the possibility to use something like `fallback => "%{[field_to_enrich]**[index]**}"` (and not to get the entire array in the fallback)

Thanks for any help. I really appreciate it.

No you cannot do that. The [code](https://github.com/logstash-plugins/logstash-filter-translate/blob/e3670bb3137437ad05a90036a90b4711a67e04ea/lib/logstash/filters/array_of_values_update.rb#L34) makes a call to Array.fill with the sprintf'd value of the fallback option.
