Как правильно описать тип в graphQL?

Question

[asd dsa]

Есть этот тип:

message DataProcessor {
    DataProcessorFunction processor_function = 1;
    google.protobuf.Struct parameters = 2;
}

Описание Структуры второго поля

// The JSON representation for `Struct` is JSON object.
message Struct {
  // Unordered map of dynamically typed values.
  map<string, Value> fields = 1;
}

// `Value` represents a dynamically typed value which can be either
// null, a number, a string, a boolean, a recursive struct value, or a
// list of values. A producer of value is expected to set one of that
// variants, absence of any variant indicates an error.
//
// The JSON representation for `Value` is JSON value.
message Value {
  // The kind of value.
  oneof kind {
    // Represents a null value.
    NullValue null_value = 1;
    // Represents a double value.
    double number_value = 2;
    // Represents a string value.
    string string_value = 3;
    // Represents a boolean value.
    bool bool_value = 4;
    // Represents a structured value.
    Struct struct_value = 5;
    // Represents a repeated `Value`.
    ListValue list_value = 6;
  }
}

// `NullValue` is a singleton enumeration to represent the null value for the
// `Value` type union.
//
//  The JSON representation for `NullValue` is JSON `null`.
enum NullValue {
  // Null value.
  NULL_VALUE = 0;
}

// `ListValue` is a wrapper around a repeated field of values.
//
// The JSON representation for `ListValue` is JSON array.
message ListValue {
  // Repeated field of dynamically typed values.
  repeated Value values = 1;
}

Подскажите пожалуйста как правильно описать поле parametrs в graphQL ?

const typeDefs = `
      enum DataProcessorFunction {
        UNKNOWN
        DEFAULT
        NORMALIZE
        NORMALIZE_AND_INFER
    }
    type DataProcessor {
         processorFunction: DataProcessorFunction
         parametrs:  ?
    }
`
