Need Help with ruby code ( I have no knowledge with ruby) on how to combine nested array objects as one Dict ? , as I am facing issues with elastic getting"Object in arrays are not well supported Error" ,

Also I tried "nested" with "mapping" and mutate - convert but nothing seems to help

Input Data:  
_{_  
\_"timestamp" : "1315294917923", \_  
_"layers" : {_  
_"data": [_  
_{"type": "8","seq": "1"},_  
_{"fixed\_value": "","fixed\_timestamp": "0x000000000001"}_  
_]_  
_} }_

I want the final data uploaded to elastic to be as

_{_  
\_"timestamp" : "1315294917923", \_  
_"layers" : {_  
_"data": {"type": "8","seq": "1", "fixed\_value": "","fixed\_timestamp": "0x000000000001"_  
_}_  
_}_

the "data" from a list is combined and converted as one Dict. Any input would be of great help

That should do it

```auto
filter {
  ruby {
    code => "
      event.set('[layers][data]', Hash[*event.get('[layers][data]').map(&:to_a).flatten])
    "
  }
}
```
