how to remove the Brackets in a json file at the end and beginning in Apache Nifi

i have a json file like this one below and try to remove the array's brackets at the beginning and the end

[
  {
    "a": "1",
    "b": "2"
  }
]

and i only want the map:

{
  "a": "1",
  "b": "2"
}

anyone knows which processor to use and how to configure? Thanks, Lukas

An alternative way might be adding a JoltTransformJSON processor which will contain this spec

[
  {
    "operation": "shift",
    "spec": {
      "*": ""
    }
  }
]

You can use SplitJson Processor.

I've used the following settings for the Processor.

Configuration for SplitJson processor

Or you can also use EvaluateJsonPath. Here is my configuration for EvaluateJsonPath.
