Logstash filter to remove a parent in a big array

Elastic Stack Logstash

I simply want to remove the parent in a big array whitout creating mute rname rules for all felds.

This is what i have now.

"timestamp": "2019-07-12T15:37:06.516Z",
"foo": {
  "bar": {
    "number": "one"
  }
},
"value1": "1",
"result": {
  "value2": "nr1",
  "value3": {
    "state": "new",
    "foo1": "bar",
    "foo2": "bar2"
  },
  "value234": "1323"
}

And what i want is:

"timestamp": "2019-07-12T15:37:06.516Z",
"foo": {
  "bar": {
    "number": "one"
  }
},
"value1": "1",
"value2": "nr1",
"value3": {
  "state": "new",
  "foo1": "bar",
  "foo2": "bar2"
},
"value234": "1323"

What is the best and simplest way to this?
