Hi 

i am using odoo 13 and when i'm trying to export product variants with specified fields i get this error . i tried to change memory limits for workers but the problem is still there
any ideas on how to properly config odoo to solve the issue ?

this is my config file

xmlrpc_port = 8069

limit_request = 8192

limit_time_cpu = 600

limit_time_real = 1200

max_cron_threads = 1

limit_memory_hard = 5368706371

limit_memory_soft = 4831835734

and this is the error that pops out every time :
