You may try to use scalar JSON type. You can find more here (based on apollographql).

• add scalar JSON to a schema definition;
• add {JSON: GraphQLJSON} to a resolve functions;
• use JSON type in a shema:

    scalar JSON
    type Query {
        getObject: JSON
    }

• an example of a query:

    query {
      getObject
    }

• a result:

    {
      "data": {
        "getObject": {
          "key1": "value1",
          "key2": "value2",
          "key3": "value3"
        }
      }
    }

Basic code:

    const express = require("express");
    const graphqlHTTP = require("express-graphql");
    const { buildSchema } = require("graphql");
    const GraphQLJSON = require("graphql-type-json");

    const schema = buildSchema(`
      scalar JSON

      type Query {
        getObject: JSON
      }
    `);

    const root = {
      JSON: GraphQLJSON,

      getObject: () => {
        return {
          key1: "value1",
          key2: "value2",
          key3: "value3"
        };
      }
    };

    const app = express();
    app.use(
      "/graphql",
      graphqlHTTP({
        schema: schema,
        rootValue: root,
        graphiql: true
      })
    );
    app.listen(4000);
    console.log("Running a GraphQL API server at localhost:4000/graphql");
