    SFTP send file smartservice> Remote File Path input parameter expects the complete file path, inluding the name of the file, which you are passing in the source document parameter. Use document() function to get the name and file extension of the source document to append it to the Remote File Path

  • We upgraded the plugin to 4.1.0 and while using the latest smart service '(SFTP) Get Remote folder Contents' replacing the deprecated smart service "Get Remote Directory Contents over SFTP", we got the below error:

    "Algorithm negotiation fail: algorithmName=""server_host_key"" jschProposal=""ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,rsa-sha2-512,rsa-sha2-256"" serverProposal=""ssh-rsa"""

    The same smart service (SFTP) Get Remote Folder Contents works fine with the Plugin version 3.0.3.

    Is there a know resolution to this error?

     

  • v4.1.0 Release Notes
    • Fixed the deprecated API's and set the minimum supported version to 23.2

  • While receiving file using smart service "Receive File Over SFTP", I am getting error as "Error copying the remote file to disk. See application server log for more details. Error Message: The message [filename] is not extractable!". It worked fist time and from 2nd time I am getting error. Also I tried next day but still getting same error.

    I am using plugin with version 2.2.1.

    Can you please suggest solution on this?

  • Can we update this plugin to be RFC compliant as it's currently not. This has become a security concern for us.

    SolarWinds highly recommends that the customer strategize and adjust their infrastructure to adhere to RFC standards and utilize clients that are up to date, as detailed in the article Resolution 2

  • Hello,

    We have been having the same issues with our connectivity to a new SFTP service. What we have found is the new SFTP service is using newer cyphers and which Appian SFTP plugin v3.0.3 does not support.
