react-app-rewired, transformIgnorePatterns on Apollo Client 3

I have a React app with:

• react-app-rewired
• Apollo Client 3.5.5

I have an error when I try to use this import:

import { MockedProvider } from '@apollo/client/testing';

If I do console.log(MockedProviderenter code here) I got: undefined.

If in my jest config I add this:

"transformIgnorePatterns": ["<rootDir>/node_modules/.*"]

It works and I got the proper console.log: [Function: MockedProvider] { defaultProps: { addTypename: true } }

That's fine, yes, but I'm getting errors in other partes of the app, like:

SyntaxError: Invalid or unexpected token

  4 | import Loader from 'react-loaders';
  5 |
> 6 | import 'loaders.css/loaders.css';

So, what could I do?

I don't get how to apply that only for Apollo Client.
