[J4v4Scr1pt]

What version of million are you using?

"1.0.0-rc.26

Are you using an SSR adapter? If so, which one?

None

What package manager are you using?

pnpm

What operating system are you using?

Windows 10

What browser are you using?

Describe the Bug

Installed latest Million and configured it as the documentation describe.
NextConfig:

module.exports = MillionCompiler.next({
	rsc: true, // if used in the app router mode
})(nextConfig);

It connects to VS and starts to collect data but my NextJs project crashes before I even see anything on Unknown element <[object Object]> in collection.
And these errors appers in the Chrome devtools:

NextJS error output:

Unhandled Runtime Error
Error: Unknown element <[object Object]> in collection.

Thanks for opening this issue! A maintainer will review it soon.

I created a new and clean NextJs 14 application and installed million. It crashes on this error:

But as soon as I remove Million from nextConfig it works again.

I would love for this to work, but million-lint feels very unstable. I tested million-lint when it was first announced also had errors then but different.

Plz let me know if I can help with anything to resolve this.

I am also facing this issue, any update on this would be appreciated.
