Any ideas how to address this?

Hi @afaik,

Can you verify the Version of the filehandling plugin in your current installation?

You can find them in KNIME ā†’ Help ā†’ About KNIME Analytics Platform ā†’ Installation Details. Click on the Plug-Ins Tab and enter filehandling in the search box:

In case your installation does not show 4.6.2 as Version, you might update the KNIME Basic File System Connectors.

Cheers,
Sascha

Hi @sascha.wolke
This is what mine shows and this matches my base installation of 4.6.1. So, is the recommendation to update my base to 4.6.2 or a later one?

Hi @afaik,

Yes, updating everything to the latest 4.6.x version should be the best way to fix this. The Sharepoint 4.6.4 plugin requires at least filehandling 4.6.2.
