WinSCP script fails to transfer file to a remote location

When I try to run a small script using WinSCP client below error throws while transferring the file to the remote server and getting aborted.

Error message

Assuming the /home/ftpuser/DK is a directory, you are missing a trailing slash. You should use:

put -transfer=ascii \\...\audit.log.2018-04-10 /home/ftpuser/DK/

When you use just the /home/ftpuser/DK, it means that you want to upload the file to the directory /home/ftpuser and save it to the file DK. What obviously conflicts with an existing subdirectory of the same name.

Quoting the documentation for the put command:

The last parameter specifies target remote directory and optionally operation mask to store file(s) under different name. Target directory must end with slash.
