Describe the bug

I encountered a build failure in my project after upgrading uploadthing to the latest version (6.10.0). The build failed on Vercel (yarn@1.22.19), in my Bitbucket pipeline (yarn@4.1.0), and on my local. After reverting to uploadthing@6.9.0 and @uploadthing/react@6.4.4, the build was successful.

Below is the log from with-tailwindcss example. It has the same error.

feels like a bug in yarn tbf

scratch that, we might be missing a peerDep.

I can confirm that the issue has been resolved in the latest version ("uploadthing": "^6.10.1", "@uploadthing/react": "^6.5.1")
