Connect TDV to AS400/IBM with FTP or file share data source, connection/introspection is verified, fetching data throws an error

[Espen Haldorsen 3]

I have created a file-delimited data source in TDV.

I have used the description in:https://support.tibco.com/s/article/How-to-use-FTP-connection-for-Delimi...

The connection is verified from studio and I am able tointrospect the file, but when i try to fetch data I get an error :

"Cause: sun.net.ftp.FtpProtocolException: CWD :550 - Specified library does not exist or cannot be accessed."

 

I have also tried by VPN and a file share with the same result. the connection is verified and am able to introspect the file, but when i try to fetch data i get an error:"Cause: Invalid username/password".

It seems to me both errors have something to do with credentials, but the connection is verified and I am able to introspect the file

What may the issue be
