tFTPConnection with Socks Proxy but no username?

[kleinmat]

Hi,
Using TOS DI 6.0.1, I need to use tFTPConnection to upload a file to a remote server via sFTP. This connection will have to go through a Socks Proxy.
However, the Socks Proxy I use does not require username/password.
But when I leave these fields empty or if I connect them to context variables which I leave empty, I get a Null Pointer Exception:

Exception in component tFTPConnection_1
java.lang.NullPointerException

How can such upload be configured?
Thanks

Hi,
Does this issue repro when you use tFTPPut only?
Best regards

Hi,
I found out what the issue was: the hostname to which I wanted to FTP connect through SOCKS had a space at the end. 
When I removed it, it worked.
I also found out how to use a SOCKS Proxy without username/password: just keep the corresponding fields at their default value of "".
