Hi @geppopompo

sorry to hear you are having problems. I would need some more information:

I assume the workflows were working as expected before? Were their any changes made to the workflow?

Versions would be great to know as well. Which local AP version are you using? And which KNIME Server and KNIME Executor Version do you have running?

Best, Iris

Hi Iris,

workflow were working before and I did not do any change in the server or the executor.
I can still load and run the workflow from Knime analytics (locally ) .

I use Knime 4.2.1 and server 4.10.1 .

Gianpaolo

The strange thing is that I did not change any things

Hi @geppopompo

can you double check for me the KNIME Server Executor Version?

If you are on 4.10.1 you should locally also use 4.1.1

I think is the same 4.2.1

Hi Iris ,

shall I move into a new server version ? I did not do it because of the risk of the new installation
but I can try to do a fresh installation

Thansk !
