    The above-mentiioned node is supported in the plugin and works perfectly in our environment. Please share with us the configured inputs for the nodes for all the input parameters like remote file path and file name

  • in reply to raghulvishnud



    I'm sorry I didn't quite get that. Would you please rephrase?

    This is what current node type is I'm trying to use:
    Send File Over SFTP (com.appiancorp.a2.process.runtime.activities.sftp.SendFileOverSFTPwithSCSUsernameAndPasswordV3)

  • in reply to Arpit Pipersaniya

    Please share us with our configurations on the node.In case of deprecated instances We have handled the code only after 2.0.0 versions, our plugin keys are SendFileOverSFTPwithSCSUsernameAndPasswordV3 and SendFileOverSFTPwithSCSUsernameAndPasswordV2.If you are referencing any other plugin keys ,for older instances please raise a support ticket with Appian to revert the plugin to the older 1.6.2 version

    SFTP node has been configured correctly as it was with earlier version. It had been working fine.

    Also, being able to file over SFTP via SecureFX.

    Need help urgently please.

  • in reply to Arpit Pipersaniya

    Please Let us Know the Smart Services Key you are trying to run.We will let u know whether it has been included in current package

  • in reply to Arpit Pipersaniya

    The error means the file path configured is either not reachable/user does not have enough permissions to access the remote server location.Please check if you are able to send the file over SFTP from WinSCP and if the issues still persist please share with us the configuration of the node and the server log file

  • in reply to raghulvishnud

    Thank you.

    After upgrade to 2.2.1 and using new nodes to connect to SFTP I’ve started getting following error: “The system cannot find the path specified”.

    Earlier(before upgrading) it’s been working fine with all same data fed to input parameters of deprecated nodes.

    Any leads, please?
