Issue/Introduction

For some SFTP Filetransfer Objects / Connection Objects the RA FTP solution in combination with the Automic Web Interface (AWI) cannot represent the target folder structure.

In the Logfile of the AWI the following error can be found:
ajp-nio-8009-exec-3    [ERROR] ENTW:1/ABC/DEF NOUI 0000000001103105  [controls.messageprovider.MessageProvider] - Error message shown to user:

Environment

Windows Cerberus SFTP Server

Cause

A problem has been fixed where the Automic Web Interface (AWI) reports an error when using the file browser on Cerberus SFTP server connections. The AWI panels of the FTP solution now allow the file browser to be used in connections to a Windows Cerberus SFTP server with disabled SSH connection set.

Resolution

Update to a fix version listed below or a newer version if available.

Component(s):
RA FTP Solution

Fix Version(s):
RA FTP 4.0.5 - already released

Additional Information

In the Trace file (generated with activated ra=9 trace flags) of the RA-FTP Agent the following error can be found:
