Hi Jason / team,

I'm getting an error when trying to run the 'Predict Random Forest From Rasters' tool. I have 20 sat bands and 1 topographic metric as my variables. Based on the image below, have I entered the Predictor Variable fields correctly?

Here's the code, thanks so much in advance:
Running script RandomForestModelPredictFromArcGISRasters...
Failed script RandomForestModelPredictFromArcGISRasters...
