["Paul Grey (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-11672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17731081#comment-17731081 ] 

Paul Grey commented on NIFI-11672:
----------------------------------

The current version of `com.hierynomus:sshj` used by ListSFTP has code that ignores the UNKNOWN type, when it is encountered.

> Certain SFTP servers have been observed to not supply file type information in their responses to remote folder enumeration requests.  This causes the current implementation of ListSFTP to return empty enumeration responses.
> Adjust ListSFTP code to enumerate files as expected in this case.
