Using Command in Rust

Challenges
1

I’m stuck on Stage #ei0.

I implemented the earlier stages and in stage IP1 I used a rust Command. I think this may be “cheating” kind of since I can pass anything to the shell now and the Command will process it. See my code below.
The weird thing is that I can’t pass stage ei0 even though locally I get the behaviour as explained by the instructions.

Here are my logs:

And here’s a snippet of my code:

_ => {
                let output = Command::new(command).args(args).output();

                match output {
                    Ok(output) => {
                        if !output.stdout.is_empty() {
                            print!("{}", String::from_utf8_lossy(&output.stdout));
                        }
                        if !output.stderr.is_empty() {
                            eprint!("{}", String::from_utf8_lossy(&output.stderr));
                        }
                    }
                    Err(_err) => println!("{}: command not found: {}", command, _err.to_string()),
                }
            }

Here’s my output:

vscode ➜ /workspaces/codecrafters-shell-rust (master) $ ./your_program.sh 
    Finished `release` profile [optimized] target(s) in 0.02s
$ pwd
/workspaces/codecrafters-shell-rust
$ type pwd
pwd is a shell builtin

Any ideas? Thanks!
