Problems setting up automated synchronization

Hello Forum
I am having trouble setting up bat driven synchronization.
First off - I know I should post a log, but I am unable to get that to work

Here is my bat

winscp.com /script=synchronize.script /log=Sync.log /parameter %1 "/var/www/%~n1%~x1"

Here is my script

# Being intended for interactive session, we are not enabling batch mode
# Connect
open sftp://me:mypassword@142.104.69.195:22
# Synchronize paths provided via environment variables
synchronize remote "%1%" "%2%"

behaviour -
cmd window pops up and immediately closes - no synchronization takes place
log file does not appear with in send to where the script lives
log file does not appear in parallel with dir I tried to syncrhonize
log file does not appear within the dir I tried to synchronize
log file does not appear at the drive root where I tried to syncronize

placing the log command after the params for the script does not change the behaviour

assistance is most welcome

Thanks

Run the winscp.com from cmd.exe console window to see the output.
