I'm sorry about this, a commit in the latest version of Remix breaks Hydrogen. We are working with the Remix team to resolve this asap. In the mean time, please pin your project to Remix 2.8.1.

@blittle Thank you for the prompt response, greatly appreciated.

Going to leave this extra bit here for anyone else who may run into this issue:
I ended up pinning all @remix/* packages in the repository to 2.8.1 which led to another error:

Error: Cannot find package 'undici' imported from /path/to/project/node_modules/@shopify/mini-oxygen/dist/worker/devtools.js
    Code: ERR_MODULE_NOT_FOUND

To fix this, just add the undici package and all should run fine.

This is the fix on Remix's end. We are waiting for a 2.9.1 release.
