Empty error message in Next.js error overlay with Next 15/React 19 deps

The error seems to be the same as #470 (it's not visible in Chrome by default. BTW Next.js should show it even so).

The error itself is safe so you can ignore it. However Next.js doesn't seem to have a way to ignore certain errors like Webpack...
vercel/next.js#13387
vercel/next.js#23970

+1 on this, really annoying in dev (love the library but the error comes up super randomly when working on T3 Chat)

+1 on this too, as I have been also working on chat app.

Two things:

1. The issue as described (Next.js showing an error that doesn't appear in Chrome console) has been fixed by the Next.js team as of 15.1.6: Fix presentation when onerror receives an event without error vercel/next.js#74643

2. I still see the errors a lot, but they also appear in the Chrome console

I was able to suppress the errors I got on page load by avoiding rendering the vlist until I had children to render in it. Sadly, when I scroll the errors still come back

Technically, I think this issue is "fixed" and a separate one might be necessary for the additional errors I am seeing. lmk what's best @inokawa

Thanks for the information. So I close this issue.

And I reopened #470 to seek possible solution and discuss further.
