"Error loading node content: null" when I open my workflow, due to if-switch

Hello,

when I execute my workflow, then save it, then close it and then open it later again, I get an error message… The message is in a Column Selection node which is in an if-switch branch which is not used. It says:

“Status: Error: Error loading node content: null”

Is there a way to solve this problem? The Point is: I can reset all nodes and then run everything and it works. But I want to run the workflow from the Knime Server and there the error message prevents the workflow from running.

Best regards

Hi @Knime_Beginner
any chance you can make us a small example workflow?
Also which KNIME version are you using? Locally and on the executor of the server.

Best, Iris

Hello,

thanks for the answer. I already solved the Problem by deleting the if-switch and doing something else.

Best regards
