I am trying to use stacking process (19_Stacking) packaged in RM distribution and encounter error "Mandatory input missing at port Stacking.base model 4)

Looking inside, the "bas" 4 expects PredictionModel. Fixes suggests "insert operator generating predictionModel", still have no clue what to do? Thanks for the help.

    Hi,
    in fact this is a false alert. This is just a small error in the meta data transformation that will be fixed with the next update. Sorry for the inconvenience and thanks for describing the error.
    You might execute the process and ignore the error, it will run without problem.

    Greetings,
      Sebastian
