Problem importing csv file with simple schema

I am having problems importing files(csv) on the client, I use simple schema for my collections, I can import csv file before with schema less collections.

My collections has a lot of array of objects and relationship with other collection, my csv file has around 90 columns, most columns has no data in it for buffer on all array object fields. It seems that simple schema is strict in terms of importing documents even if I set blackbox: true for all the array of object fields to see if it’s working.

Is there another way to achieve this using simple schema?
