unable to connect - open command has too many arguments

Hello, I'm trying to setup a connection for POC that I'll then modify so that it connects to an external vendor and retrieves a file for us. I looked through some recent posts and saw similar questions but it didn't look like they applied exactly. I've been using the open command page and the session url, and useful scripts pages for assistance on the command and syntax. Here's the error I'm getting...

I have connected to this host with the gui so I know connectivity works from host a to host b, and that it's not the first time they've shared files...

File (currently):
option batch abort
option confirm off
open sftp://user:password@host.company.com -hostkey="ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
get "test.txt" "C:\Program Files\Winscp\test.txt"
exit


Error (before -hostkey argument):
C:\Program Files\Winscp>winSCP.com /script=test.txt
batch abort
confirm off

Continue connecting and add host key to the cache?

Error after using the -hostkey

C:\Program Files\Winscp>winSCP.com /script=test.txt
batch abort
confirm off
Too many parameters for command 'open'.

Thanks!

See https://winscp.net/eng/docs/faq_script_switch

If that does not help, please attach a full log file showing the problem (using the latest version of WinSCP).

Thank you, I upgraded and then was getting an error about use open command instead of deprecated command line parameter, that was interesting because I was trying to use the open command but I found another thread in the forum where you linked another support page, and that resolved the connection and file transfer problems.

cheers!
