Hey everyone, I see this has come up a few times before, notably in #1264

I am still getting these errors even after running yarn rw upgrade about five minutes ago.

yarn rw test is failing with this error:

  ● Test suite failed to run

    Cannot find module 'whatwg-fetch' from '../node_modules/@redwoodjs/core/dist/configs/browser/jest.setup.js'

      at Resolver.resolveModule (../node_modules/jest-resolve/build/index.js:306:11)
      at Object.<anonymous> (../node_modules/@redwoodjs/core/dist/configs/browser/jest.setup.js:5:1)

Looks like I'm running v0.21.0. All of my web tests are failing, including the boilerplate ones from running the page generator like: yarn rw g page home. API tests are all fine.

Are there additional steps I need to take in upgrading, beyond yarn rw upgrade? Or is something still broken here? Thank you!
