Node.js Error - FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

If you are like me, stuck with this error : FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

It's an error of a too big object that is trying to be saved in memory (RAM).

Step to reproduce :
