WalkDir returns paths that "don't exist"

Question

I'm creating a tool to find certain files, and I'm using WalkDir to iterate over every file from root. But when I try to pull the metadata from the file (Using fs::metadata), it says that there is "no such file or directory."

Here's my code:

use std::fs::metadata;
use walkdir::{DirEntry, WalkDir};

fn is_not_hidden(entry: &DirEntry) -> bool {
    entry
         .file_name()
         .to_str()
         .map(|s| entry.depth() == 0 || !s.starts_with("."))
         .unwrap_or(false)
}

pub fn find() {
    WalkDir::new("/")
        .into_iter()
        .filter_entry(|e| is_not_hidden(e))
        .filter_map(|v| v.ok())
        .for_each(|x| {
          let data = metadata(x.path()).unwrap();
          println!("{:?}", data);
        });
}

And here's the full error message:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/ezfile.rs:18:41
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Any help would be greatly appreciated :)
