Problem with XY to line

[ClementSct]

Hey !

First of all, thank you for your tool !
I'm currently using the "XY to line" function to do a flow map between several zones. I've retrieved the X and Y coordinates of each zone (x_origin, y_origin for the departure zone and x_dest and y_dest for the arrival zone). When I use "XY to line", it builds lines between each centroid, so everything seems to work. However, I've found that it doesn't build all the lines (for example, I have 406 lines that are supposed to be created and only 289 are built). Maybe it's too much for the function ?
Do you have any idea where the problem might be coming from ?

I am no longer working on this project, but if I could guess, there is probably something wrong with some of your features. The function can handle millions of records.
