I am attempting to use the STFP module in order to export an excel file from my project to a remote location automatically. I seem to be running into some errors when trying to save my SFTP configuration.  I direct to host, port, I get a host fingerprint key and put in both username and password in the authorization. When I try to save the configuration I get the error: Key should not be empty. I attempted to use a public and private key file combination as well and got the same error.   I am at a loss at the moment, anybody have some ideas as to what is going on? Error message and stack trace below: An error has occurred while handling the request.
