Debugging transfer task running in Windows Scheduler, SSIS or other automation service

First step in debugging, is to make sure the task works when executed independently. Execute the exact command that you have configured in Windows Scheduler/SSIS in Windows Command prompt.

For example, if in Windows Scheduler you have "C:\Program Files (x86)\WinSCP\WinSCP.exe" in Program/script and /script="c:\script\example.txt" in Add arguments, try to execute following full command in Command prompt:

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /script="c:\script\example.txt"

If the task works correctly from Command prompt, see My script works fine when executed manually, but fails or hangs when run by Windows Scheduler, SSIS or other automation service. What am I doing wrong?

If the task fails even from run from Command prompt, inspect an output of the task for any error. If you see an error, check list of common error messages or search this website for the error.

If the problem is not obvious from the output, enable logging to a file as described below.

Next step is to enable logging to file (you should have logging enabled anyway) and inspect the log. Use /log command-line parameter.

For example in Windows Scheduler the Add arguments may look like:

/script="c:\script\example.txt" /log="c:\script\example.log"

Full command to be executed from Command prompt is:

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /script="c:\script\example.txt" /log="c:\script\example.log"

If you know that the task failed with exit code 1, see Why is WinSCP returning non zero exit code? to learn what to look for in the log.

• Why does WinSCP not work in a new environment (operating system, machine, user account, network), when it works for me in a different environment already?
• How do I know that script completed successfully?
• Why I cannot connect/transfer using script, when I can using GUI (or vice versa)?
