Recoil: Duplicate atom key warning when used from multiple bundles

For 0.0.8, I am getting the following blocking error (was working fine with 0.07):

recoil.development.js:117 Uncaught TypeError: Cannot destructure property 'error' of 'undefined' as it is undefined.

Two issues afaics:

It displays the wrong error, since there isnt a third parameter in the call from registerNode: https://github.com/facebookexperimental/Recoil/blob/22b42bbc0366bf748b4265735eb4b6c90c90ff1f/src/core/Recoil_Node.js#L84
The actual error (Duplicate atom key …) it wants to display is not correct, since I have only one of this key registered (it is not duplicated), however the package is called from two bundles.

Hi all, I got this warning when trying Recoil with NextJS. This happens every time I try refresh with new page.

I think it might be HMR problem because it happened on development only, but I want to know how I do a singleton pattern for atom to prevent this warning on development.

Thanks!

I am using hmr however the error shows without hmr being invoked (no files are changed, just loading the app generates the error)
