I am starting with a list of distances between points and trying to create a list of cumulative sum of their distances. The calculation I have implemented is unable to finish and begins returning null in the middle of the list. For some inputs it will fully complete and for some it will begin return…

@AmolShah ’s code in DS [sum_2021-10-02_02-03-31] toSum; [Imperative] { num = []; sum = 0; for (i in toSum) { sum = i + sum; num = List.Flatten([num,sum]); } return num; };

List.Scan used for cumulative sum does not complete and returns null
