Thanks @natasja. Copying the node over shouldnt make any difference, so it looks like the problem is something to do with exactly how the SDF file is formatted.
Could you use this ‘component’ in your workflow at the same place as the node which is breaking?
You will need to select ‘configure’ on this node, and change the dropdown to the sd-file column in your incoming table:
It should run until it reaches a failing row. The sd-file of that row will be saved in your knime workspace in the folder containing the workflow (if you don’t know how to get to that, please let me know and I will show you). Please attach that file back in a reply.
Thanks
Steve
