Connecting to SFTP Server--ERROR: Invalid data type, INTEGER(02) is expected, but was 1D

Hi everyone,

i am using the UiPath.FTP.Activities to connect to an SFTP Server.
i have an private ssh key and an password.
When i try to connect with WinSCP the connection is possible but when i try to connect with the activities i get the errror:
“FTP Scope: Invalid data type, INTEGER(02) is expected, but was 1D”

everything is up to date
i have the Use SFTP checked
