NRE with SynchronizeDirectories()

I am able to get WinSCP to throw a NRE internally by doing a SynchronizeDirectories() Sftp from a remote directory containing 90k files to a local directory containing 30k files. I can assist by running a debug version or provide you with log files if you wish.

Here is some more info:
It is throwing in Session.cs because _process is null.
Here is the call stack:

Re: NRE with SynchronizeDirectories()

Please set Session.DebugLogPath and Session.SessionLogPath and submit both logs.

Submit the log with your post as an attachment. You may want to remove data you consider sensitive. If you do not want to post the log publicly, you can mark the attachment as private.

Log files

I set those two properties. Unfortunately it only created a debug log and not a session log. I have attached the debug log. Does that help?
  • debuglog.log (57.88 KB, Private file)

Re: Log files

You cannot use .xml extension for a session log. Please using anything else, like .log.
