ExecuteCommand fails on AS400/IBM i-series after GetFiles

I'm using WinSCP 6.5.5 .NET assembly in PowerShell script.
In my script I did these tests:

1. launch just one or more commands using the ExecuteCommand: works fine
   
2. launch just one or more commands using ExecuteCommand and transfer a file with GetFiles: works fine
   
3. launch one or more commands using ExecuteCommand, transfer a file with GetFiles and relaunch a command with ExecuteCommand: this last command fails
   
4. if I remove GetFiles the last command works fine
   

Can anyone tell me what the problem is?
I'm attaching the following files:

• PowerShell script
  
• Execution result
  
• winscp.log
  

Did you try to set FtpWorkFromCwd to on? Can you post log file for that?

Hi Martin, with FtpWorkFromCwd=on both the commands are working, but not the file transfer.
Instead with the parameter FtpWorkFromCwd=auto the file transfer works but not the second command.
I'll send you both logs.
Best regards
