This sounds a lot like #4843. Try upgrading apollo-boost to 0.4.4 and see if that fixes it

Thanks for the advice @maithanhnhan 🙏 . I've ran yarn upgrade-interactive --latest and upgraded all dependencies to their latest version. Also made some required upgrades, since latest next js version has TypeScript support. All good so far, but now I'm getting syntax errors:

[ error ] ./pages/_app.tsx
SyntaxError: /Users/zomars/Sites/next-shopify-storefront/pages/_app.tsx: Unexpected token (8:9)

Nevermind. I've reverted all my changes and just upgraded apollo-boost and it's working now. I'll make a PR with this change. Thanks!
