Error when loading workflow with “Network to Row” node

Hello,

I am creating a workflow in KNIME using the “Network to Row” node. However, whenever I try to open my workflow, it restarts from this node, i.e. it does not save the changes and the following error appears.

I have already tried to uninstall and reinstall the KNIME Network Mining extension, but the problem persists. I have also updated KNIME to version 5.4.2, but I am still unable to resolve the issue.

I would appreciate your help in solving this problem. Thanks in advance!
