      key[0] : { 
            field1 : String,
            field2 : String
    }

input request {
       Keys: [String]
    }

     "key1" : {
           field1 : "value1"
           field2 : "value2"
      },
      "key2" : {
           field1 : "value1"

Got Answer in following post:

Apollo/GraphQL field type for object with dynamic keys

Here is the summary:

GraphQL relies on both the server and the client knowing ahead of time what fields are available available for each type. In some cases, the client can discover those fields (via introspection), but for the server, they always need to be known ahead of time. So to somehow dynamically generate those fields based on the returned data is not really possible.
