How to use legacy scp

[Jackolix]

I'm attempting to retrieve a file from a firewall device that only supports legacy SCP.
When trying to download the file, I encounter the following error:
WARN net.schmizz.sshj.xfer.scp.SCPEngine -- SCP exit status: 128

This error suggests that there might be an issue with the specified file path.
I had a similar problem with scp on linux. He could find the file either because he was using sftp instad of legacy SCP
