Shopify Sync errors

Hello,

I am not able to sync my shopify account with my wordpress site.

Using shopify 2.2.6

The link shows what happens when I click on a product.

Lite sync is not selected (sync posts is)

Items per request is set to 25

Synchronised requests is checked.

I get this error message:

Server Error: The maximum amount of server memory was exceeded.

Stopped at 24.3MB of a 1MB limit.
This occured while calling: WP_Shopify\Processing\Vendor_Background_Process::memory_exceeded on line 634

?? Please check our documentation for possible solutions to this specific error.
