Download / Upload from list node fails while connecting via SSH

KNIME Extensions
1

Hi,

I recently upgraded my Knime to 3.6.1 from 3.5.3 and since then I am having trouble using the node “Download / Upload from list”.

I am using an SSH connection node to supply the connection information. When I execute the “Download / Upload from list” node I get the following error -

ERROR Download / Upload from List 0:4 Execute failed: Protocol file incompatible with connection information protcol ssh

The knime log has the following error

I have tried checking the connection using the “List Remote Files” and I am able to browse through the remote files.

Please help me understand what the error is and how to resolve this.

Hi @jaisonbabu,

Could you provide an excerpt from your input table with the locations? It sounds to me like the URI are not correct.

Hi @stelfrich,

I am sorry, I did not understand what you are asking here. If it’s the connection detail, I cannot provide you since it’s connecting to a client.

I’ve uploaded snapshot for your reference.

I reverted the Knime to 3.5.3 and the workflow works perfectly fine without any changes. I believe it is some changes in 3.6.1 that has caused this failure.

Let me know it this helps.

Best Regards,
Jaison

I was able to reproduce the exception, @jaisonbabu. We are looking into this and will keep you update here!

For now, the workaround (as you have already figured out) is to use KNIME 3.5.3…

Best,
Stefan

We have a similar problem, has there been any progress?

Can you provide a legacy node for this if there is no immediate solution? It’s not really feasible for us to keep both 3.5 and 3.6…

Hi @David_Ko,

This has been fixed on master and will make its way into 3.6.2 (which will be released in the next weeks).

Thanks, look forward to it.

We are using the KNIME server, would going to 3.6.2 require any upgrade of the server itself?

You will have to update the executor (which is a KNIME Analytics Platform) if you want to execute workflows that use the node on KNIME Server.

3.6.2 has been released.

@David_Ko @papaito Can you confirm that the issue has been solved? Thanks!

The new release 3.6.2 worked for me. Thanks
