  • Hi Iván García, 

    We will analyse the issue and get back to you.

  • Good morning,

    Any updates about this? We need to deploy this functionality as soon as possible and this is blocking the deployment. Thank you.

  • Hi,
    Please share us with the steps to reproduce the issue because we cannot reproduce the issue from our side. Thanks.

  • Hi,

    We are getting that error when trying to upload files with size of 8kb or more to an external SFTP server. Other uploading methods against that server (for example, via sftp utilities or cmd) work fine. Sent attached an example of a file that shows the problem when uploading through the plugin, but with the command line tool it is uploaded succesfully.

    Sorry for the delay. We were analysing this issue but in between we got stuck with other priority work items. We will look into this issue once we complete them and we will reply you by early next week

    But if I verify the Appian Folder (Destination Folder) the document already appears. How I could control this issues?
