Shopify Sync Error (Default Supplier)

Hi,

I have received this error on my first sync to shopify. Any idea on how to fix this?

Traceback (most recent call last):

Seems custom fields were not sync properly.

Please run bench --site migrate

The error still persists after running bench --site [site] migrate.
