Hello,
I'm trying to install devtools in the Next.js 14 app router, but although the UI is displayed properly, when I try to open the devtools, I encounter the following error. What could be the issue?

Uh-oh, something went wrong.
If you believe this to be a bug, please file an issue on [Jotai DevTool's GitHub repo](https://github.com/jotaijs/jotai-devtools/issues) with a minimal reproduction and the following error

TypeError: values.map is not a function

That's strange! I can take a look at it. Could you please create a repro on CodeSandbox?

Thank you! CSB is breaking for me, its not able to find useAtomValue from jotai/react which is strange. I'll take a deep look later.

I think nextJS 14.1 is also breaking other stuffs for jotai. atomWithStorage also doesn't seem to work properly, I'll try to reproduce it and if successful will cut an issue on the jotai repo

I have created an issue and provided the reproduction project in #127

I have the same problem with ^14.1 while my other project running 14.0.2 still works so I'd recommend downgrading to 14.0 for now

Oh... Looks like there might be a problem with version 14.1... Thank you for your response. I'll keep it in mind
