Hello,
I’m trying to control the GroupBy node via variables. To do this, I create a list of columns and a list using the aggregation method. Nothing special.
GroupBy config:
Unfortunately it does not work. I get an “out of bound” error:
I am using KNIME 5.2.1
When I reduce the number of columns to one (still a list type), it works, but with multiple columns (see pics above ) not.
(Yes, I checked the other topics of this forum, but no solution found.)
Thank you in advance.
