App only syncing certain Shopify orders

[Igniteou5]

I am having trouble getting ecommerce_integrations to properly sync orders from Shopify to ERPNext.

I have tried narrowing down the sync range down to this month where we definitely have a few orders, however, even after waiting for XX:00 hours for the sync_sales_order process to start, it does not appear.

Whereas if I increase the range to from last year till now, it starts to sync at XX:00 hours, but only managed to sync 1 order before the next gave an error due to a deleted product on an old order (issue #337).

Maybe the error is stopping it from syncing everything, but I believe it should still be able to sync this months' orders. New orders sync and cancel just fine. Products also managed to sync with the 'Import Products' page.

I am also getting similar issues to #298 #320 where it will queue up 'migrate_from_old_connector' after saving Shopify Settings.

Here is my log for reference.

I am running self-hosted ERPNext version 15 branch & the main branch for ecommerce_integrations.
