• Summary
  While working on a project with Apollo Client 3.8, I've encountered a type incompatibility issue between the type of ApolloLink and the return type of withScalars. Specifically, the types of the fields split, left, right in ApolloLink appear to be incorrect.

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

the type returned by withScalars is an ApolloLink that comes from

import { ApolloLink, FetchResult, NextLink, Observable, Operation } from "@apollo/client/core";

@apollo/client is a Peer Dependency (marked as "@apollo/client": "3.x"), so it will use whatever version you have in your app.

I have checked in my app, and works fine for me. It uses:

• in package.json

"@apollo/client": "~3.8.8",

• in yarn.lock:

"@apollo/client@~3.8.8":
  version "3.8.8"

If you are able to provide a repo where I can replicate the error, I could investigate further.

Cheers!
