Hi, I'm following the documentation [1] of window functions with incremental aggregations, but I'm getting an "input mismatch" error.
The code [2] is almost identical to the one in the documentation, at the bottom you can find the exact error. What am I missing? Can you provide a working example of a fold function with both a FoldFunction and a WindowFunction?
