Receiving the error:
The given key was not present in the dictionary.com.uc4.ftpjob.DataTransferException: Error during opening file /XXXX/XXXXX
When running a RA SFTP job to download a file.
Release : 12.3
Component : AUTOMATION ENGINE
This error is an indication of a key either not in the request or not matching. The dictionary is the collection object and the key is how to specify the value you want from that collection object - that collection object can contain multiple values.
This needs to be discussed with the owner of the external FTP site.
