Error when loading workflow with “Network to Row” node

[elier_abreu]

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!

Dear @elier_abreu,

Thank you for reporting the problem.
This was already known and now fixed in KNIME Analytics Platform 5.5 which will be releases soon:

Subgraph Extractor (Saved Workflow Issues)

Hi @ScottF , I’m referring to this unsolved but closed thread on → this post ← I am having the same issue and it produces the same error with this node. I can save a workflow completely, but everytime I reopen that workflow, the node resets with that error shown. I’m using Knime 4.6.3. Here’s a screenshot: [pa]

Would you please try agian in 5.5 (when released) and let us know if the problem is solved?
