When I exclude the “Current Overall Grade” column in my KNIME workflow for an academic analytics project, I get an execution error. I tried removing that node as a way to focus solely on behavior predictors. But when I do so, all the downstream ML nodes stop executing & I can’t view the results. I think it is either a configuration conflict or some sort of dependency issue with the learner node. Regardless, when I reset those nodes, the problem continues. In the interim, while attempting to share my .knwf file (I’ve been getting upload errors), I’m posting screenshots
of both the node setups & the specific error messages being shown in the console.
