Hello guys,

I know there is a boatload of threads about this topic, but unfortunately i cannot resolve my issue.  
I have an index that has this mapping:

```auto
"debug": {
	"properties" : {
		"input" : {
			"properties" : {
				"request" : {
					"properties" : {
                     ...

```

So, `debug.input.request` is an object. Sometimes this field comes has a string and i am not being able to create new field to store this value when it is not an object.  
Currently i have this on my pipeline but it is not working as i expected:

```auto
if [debug][input][request] {
        ruby { 
            code => 'event.set("debug_input_request", event.get("[debug][input][request]"))' 
            remove_field => ["[debug][input][request]" ]
        }
    }

```

The logstash error in question is the following:

```auto
"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"object mapping for [debug.input.request] tried to parse field [request] as object, but found a concrete value"

```
