Error when loading workflow with "SubGraph Extractor" node

[gnangnan]

Hello I have built a workflow that uses the “SubGraph Extractor” node and when trying to load it, I have the following error:

Status: DataLoadError: Unable to load port content for node “SubGraph Extractor”: Data cell implementation ‘org.knime.network.core.knime.cell.GraphCell’ not found.

You’ll find my example workflow enclosed. When I execute the node again everything works as expected. What do I need to do to have this workflow loading properly?

Hi @gnangnan -

Thanks for the example workflow and the detailed description of the problem. I can reproduce it using KNIME AP 4.3.3 on my end. This definitely feels like a bug - let me ask internally to see what I can find out.
