SFTP Smart Services Plugin

Hey,

I have a problem with this plugin https://community.appian.com/b/appmarket/posts/sftp-smart-services#

Looks like there is something with Send File over FTP node, retrive files works ok but send one has some issues. IMO iI put wrong value into Remote File Path - I've read documanation but i saw there is some function to get docname can someone please tell me how this node input should looks like? Currently i have this error in pv!error :

 This is my document name

Thank you in advance
