I am going to get a file through SFTP server. However, the certificate key file is in ppk format. It seems not accepted with ppk format. What file type should I change?
Please check this …this shows what is accepted and how to convert
If you are working with UiPath and need to use a private key file in PPK (PuTTY Private Key) format to connect to an SFTP server, you might need to convert it to another format that UiPath supports. UiPath primarily uses the OpenSSH key format (usually with a .pem or .key extension) for SFTP connections.
Try Converting the ppk file to openssh format. Then pass the path of the converted file to Client Certificate field. It will work.
