Why is WinSCP returning non zero exit code?

When checking results of your script you may encounter non zero exit code, indicating error, for reason that may not be obvious to you.

Sometimes the exit code indicates error even, when you consider outcome of the script successful. This is usually caused by a syntax error in the script command that is not essential for the overall script task.

Inspecting Script Output

If you are able to reproduce the problem, when running the script in console window, check the script output for any errors.

In the example below you can see that although the connection and file transfer finishes successfully, the attempt to set script option confirm to yes (instead of valid on) is the reason, why script exits with code 1 nevertheless.

Inspecting Log File

If you are not able to reproduce the problem, when running the script in console window, at least try to enable session logging, e.g. using /log command-line parameter. Once the script finishes, search the generated log file for message “Script: Failed”, which should immediately follow the cause of the problem.
