while generating sample data with the following input file:

I followed the steps stated at https://github.com/PrestaShop/performance-project/blob/master/shop/README.md, and I stopped ad the last of point 1, I changed the values according to what I have on a very similar Prestashop instance.

After the error, the generated directory contains the following files:
