Steps to Reproduce the Bug or Issue

1. Run Application
2. Go to http://localhost:3000
3. Select files to upload
4. Hit submit button
5. See validation errors

Expected behavior

I expected validation to pass when files were uploaded. They are coming in as an array of file instances so i don't know why its failing.

Screenshots or Videos

No response

Platform

• OS: macOS
• Browser: Arc
• Version: 135.0.7049.116 (Official Build) (arm64)

Additional context

The two important files are: src/app/page.tsx src/server-actions/submit.ts

I implemented a non working (using zfd) and working version of the server action. For the working version i just made a custom zod type that worked the way i expected zfd.file() to work.

Hi!

I cloned the repo, but everything appears to work fine as far as I can tell. What version of node are you using?
