Hi all,
I am new to IPFS,
I am trying to push a file to IPFS Network, using shell command,
in my rust code.
following is the code i am running

let mut output = Command::new("/usr/local/bin/ipfs")
        .arg("add")
        .arg(filename)
        .output()
        .expect("failed to execute process");

    if output.status.success() {
        let cid: String = String::from_utf8_lossy(&output.stdout).to_string().split_off(6).split(' ').by_ref().take(1).collect();  
    
        // Load AWS credentials from environment variables.
        let config = aws_config::load_from_env().await;
        let table_name = "cid_table";

And this code is configured to run as service.
Problem: I am able to get the cid, but not able to get the file with the returned cid.
and when i try to upload an empty file, I am able to get the cid and also i am able to retrieve the file from IPFS network.

Please suggest
