SFTP Smart Services

Hey, 

We are using the "SFTP Smart Services" (v3.0.2) - (SFTP) Send File [Smart Service] and I believe that I have set it up correctly, but unfortunately I am getting "Auth cancel" error message. 

I am not sure where the connection / authentication is failing as it's not obvious from the error log. Previously we were able to make a connection successfully using the old version of the plugin. (now the previous version of this plugin is also failing, so we are updating to the newer version) Also, there has been no change on our infrastructure end. 

I can also confirm that I am able to make the connection successfully using another "cross-platform FTP application" (FileZilla).

Below are the setup details for the (SFTP) Send File smart service which I am using:

Node's Data Inputs:

File Transfer Configurations: 'type!{plugins.ps.appiancorp.com/.../}FT_Config'(
serverHostName: "xyz-abc.au",
serverPort: 22,
scsExternalSystemKey: "thirdparty-cred-sftp-key",
usePerUserCredentials: false(),
privateKeyFile: "private-key-doc"
)

Remote File Path: "/home/xyzabc" | Type = Text

Document to Send: "testDoc" | Type = Document

NOTE: privateKeyFile parameter is a document.

Below is the error message on the system logs:

2023-08-31 00:36:51,263 [Appian Work Item - 7735 - WorkID 624 - execution02 - process 537169099 - model 27606 : UnattendedJavaActivityRequest] ERROR com.appiancorp.ps.plugins.filetransfer.sftp.SendFileOverSFTP - com.jcraft.jsch.JSchException: Auth cancel

Any help on this issue would be much appreciated!

Kind regards,

Hi Tanisha,

I was getting the "Auth cancel" error cause our server (on which the file needs to be transferred to) was updated with new public/private key exchange algorithms and this plugin only supports the old exchange algorithms. So, we reverted back the changes which we did on the server to be able to use this plugin - which worked for me. 

Kind regards,
Ankit
