GraphQLModule.forRoot({
      context: ({ req, connection }) =>
        connection ? { req: connection.context } : { req },
      playground: true,
      debug: true,
      autoSchemaFile: 'schema.graphql',
      installSubscriptionHandlers: true,
      subscriptions: {
        onConnect: (connectionParams: any) => {
          return connectionParams.Authorization;
        },
      },
    }),
