Issue/Introduction

Agent RA FTP was replaced with the new Agent IG_FTP 21.0.0 and since then all JOBS SFTP that use a private key authentication don't work anymore

The root cause seems to be written in the Report as the file path is not shown:

Using SFTP private key file: null

In the PLOG log we can find the following errors:
