Error when FTP folder is empty EnsLib.FTP.InboundAdapter

Hi community,

I've created a BS that uses FTP InboundAdapter. It works, read the file and process it.

The problem is when there not any file in the FTP folder, it raises the following error:

ERROR <Ens>ErrFTPListFailed: FTP: error en List para *.csv (mensaje='No-transfer-time exceeded. Closing control connection.',código=421)

I think it is something about the configuration, but I don't find what is the problem.

Any idea?

Best regards,

Francisco Lopez

Dear all... problem solved.

I've created a new FTP server (based on IIS) and it works without problem.

The previous one was created with Filezilla server.

Fortunately, the client has an FTP server based on IIS, so with this test we consider the integration in their preproduction environment will be fine.

Note: I've changed the "Server List Style" to "MSDOS" for this new server ;)

Thanks to all for your time.

Best regards,

Francisco López

Hello Antonio

Yes, I am using a custom BS, I have overwritten OnProcessInput from EnsLib.RecordMap.Service.FTPService because I want to store the content in a table instead of processing each line.

This service works well until we have changed the FTP server, so I do not know if it's a problem about Passive mode, or anything

Hi Francisco,

Have you tried to use a custom BS so you can check if the file really exists? Or at least to identify when exactly the error is being generated?
