Describe the bug

Hi, I'm nu new, so I'm writing a bunch of stuff that doesn't work yet 😅 I have a script that is using string interpolation to build a list of paths, and then is trying to open each path.

When I run my script, I'm getting a "directory not found" error pointing at my string interpolated value, but it doesn't tell me the evaluated value that causes the error, so it's hard for me to know what the problem is.

Here's my script:

def main [rust_project_dir: path] {
    open $"($rust_project_dir)/Cargo.toml" | get workspace.members | each { |crate|
        open $"($rust_project_dir)($crate)/src/lib.rs"
    }
}

I'm running it as nu script.nu /path/to/my/rust/workspace, and I'm getting this error:

Error: nu::shell::eval_block_with_input

  × Eval block failed with pipeline input

   ·                                  ╰── directory not found
 4 │     }
   ╰────

How to reproduce

1. Write a nu script with a loop that uses string interpolation to build filenames and then open each file.
2. Remove one or more of the files that the script expects should exist.
3. Run the script and observe that the error message doesn't say what the actual, evaluated value is that caused the problem.
4. Imagine not knowing which file was removed and despair :)

Expected behavior

I expected the error message in my particular case to say something like directory "/Users/carolnichols/rust/my-workspace/foo/src/lib.rs" not found; somewhere showing the actual value passed to open that caused the problem.

Configuration

Additional context

I think I'm also hitting #10085 as I think this error should be "file not found" rather than "directory not found". I didn't find an issue that was exactly what I'm reporting here when I looked.
