Can you please help us what could be the root cause or do we need to change any configuration from our end or update the plugin to latest version. Please find the attached screenshots for your reference to understand the issue and error clearly.

Hello, we are trying to connect to an sftp client using this plugin. With the same data (host, port) and credentials with which we can access through filezilla, appian always returns timeout. Both using the endpoint as a host (connection through the configured Appian IPsec tunnel), and with the host the sftp IP (without VPN, only through the Internet, we have Appian on cloud). It may be due to this parameter configured in the SFTP (it already happened to us with another plugin): require_ssl_reuse = true??

Thank you.

I'm working on (SFTP) Get Remote Folder Contents.

Some one please help me with the File Transfer configurations. I've already gone through the attached document but there is only one line information about this.

Currently we upgraded our SFTP plugin to version 4.1.0. Configured the plugin to use the File Transfer Configurations with the proper mappings as below

'type!{plugins.ps.appiancorp.com/.../}FT_Config'{

serverHostName:"text value",

serverPort: 22,

scsExternalSystemKey: "text value",

usePerUserCredentials: false(),

privateKeyFile: "document"

}

we get the following error in the logs

ERROR com.appiancorp.process.engine.UnattendedJavaActivityRequest - An error occurred while executing activity: id=704, classname=com.appiancorp.ps.plugins.filetransfer.sftp.SendFileOverSFTP

The old version of the plugin with the same credentials works fine

Appian 24.4

SFTP Utilities 4.1.0

I am trying to connect with an SFTP server using a passphrase-protected private key.

The private Key contains the lines:

[embed:dc8ab71f-3b98-42d9-b0f6-e21e02a0f8e2:5542a8c5-5c91-4627-9924-a9ae8d2b3487:type=text&text=PuTTY-User-Key-File-3%3A%20ssh-rsa%0AEncryption%3A%20aes256-cbc%0AComment%3A%20rsa-key-20240730%0APublic-Lines%3A%2012%0A...%0AKey-Derivation%3A%20Argon2id%0AArgon2-Memory%3A%208192%0AArgon2-Passes%3A%2034%0AArgon2-Parallelism%3A%201%0AArgon2-Salt%3A%2025ae650a118fe9de89eccbe43fc34e0f%0APrivate-Lines%3A%2028%0A...]

I have configured the FT_Config to use an scsExternalSystemKey and reference the above private key file.

in the third party credentials I have included the fields "username" and "passphrase"

In the tomcat logs I'm receiving the error:

UnattendedJavaActivityRequest] ERROR com.appiancorp.ps.plugins.filetransfer.sftp.ReceiveFileOverSFTP - com.jcraft.jsch.JSchException: 'argon2' is required, but it is not available.

I have tried adding "argon2" as a field in the third party credentials, but same error occurs.

Using version 4.1.0. When using the (SFTP) Receive File smart service, if a file path is invalid/file doesn't exist the plugin is still creating an empty file with the Document Name in the Destination Folder. The output Error and Success are set but New Document is blank (even though empty doc created). Destination Document input is not being used in this scenario.

Hi, we're using version 4.1.0 and we'd like to be able to enabled Debug/Trace lvl logging for the plugin since we're encountering an issue when moving files to a different location on the filesystem. We've modified appian_log4j.properties with the following entries, but still see no logs in tomcat-stdOut.log:

log4j.rootLogger=ERROR, CONSOLE, METRICS log4j.logger.com.appiancorp.a2.process.runtime.activities.sftp=DEBUG log4j.logger.com.appiancorp.ps.plugins.filetransfer.sftp=DEBUG log4j.properties.com.appiancorp.ps.plugins.filetransfer.sftp.SendFileOverSFTP=DEBUG

Can you please let me know the precise entries that we should put in log4.properties file in order to get enhanced logging for the plugin?

When we upgraded the plugin from version 3.0.3 to the latest version that is 4.1.0, we started facing the following error:

Please advise.
