Global Importance Feature does not work in crossvalidation

Hi all,

i am trying to compute global importance among model predictors.

I ran a gradient boosted tree model and i followed (as it looks like to me) all the steps needed by reading knime XAI guide.

Despite of this, the node does not work properly.

May it be related to cross-validation loop wrong setting ?

I set a workflow start-end couple of node in order to link it to the global importance node, but i think i am wrong in something i don’t know…

Here my workflow
