ExecutionResult Type Error still on Tag 3.0.0-beta.48

[BrickCarvingArtist]

On tag 3.0.0-beta.48
Would you please change code in file /src/core/QueryInfo.ts to code below?

on line 2 to change

import { DocumentNode, GraphQLError } from 'graphql';

line 10 to add

import { FetchResult } from '../../client/link/core/types';

and function markResult() to change to like

function markResult<T>(result: FetchResult<T>, ...) {}

Intended outcome:
Do not throw type error.

Actual outcome:
Throw type error.

How to reproduce the issue:
Just compiled by typescript.
