Error while uploading file

[HakanL]

However it would be good to properly catch and report the error, instead of null-ref :)

Sometimes if I retry it works, with nothing changed.

@HakanL, seeing that I'm not familiar with BalenaOS, there are a variety of remote-side causes that could be triggering this. None the less, let's work through this and see what we can do.

• Which version of the extension are you using? (assuming the latest published)
• Are you able to test/validate connectivity using SFTP via a 3rd-party tool?
• Are you connected to a physical device or virtualized one?

Your issue appears to be happening right at this point (SshToo.cs - Lines 487-493). This is where I'm calling Renci.SshNet's SFTP to perform the upload.

Since this is happening "sometimes" triggers the question, is the remote OS dropping the SFTP connection?

            Logger.Output("Uploading...");
            await Task.Run(() =>
            {
              tarGzStream.Seek(0, SeekOrigin.Begin);

              sftp.UploadFile(tarGzStream, pathBuildTarGz);
            });

            Logger.Output($"Uploaded '{_tarGzFileName}' [{tarGzSize,13:n0} bytes].");

Which version of the extension are you using? (assuming the latest published)
Yes, latest published

Are you able to test/validate connectivity using SFTP via a 3rd-party tool?
I haven't tested this, but I'm SSH:d to the device (using putty)

Are you connected to a physical device or virtualized one?
It's a physical Raspberry Pi CM4, but it's running docker so I'm attempting to deploy to a guest instance in docker (and that's where I'm also SSH:d into). But it works intermittently.

How would I see if the remote OS drops the SFTP connection?

It may have been an issue with my Raspberry Pi, it's been working fine now for a while, so I'll close this issue.

None the less, we can get in that checking mechanism. Definitely don't like seeing unexpected errors
