Products getting skipped during Printful order fulfilment

[shahthepro]

Pundi X reported a bug where an order had different products shown in Dshop and in their Printful dashboard.

A buyer had placed an order for two products. On Dshop, both showed up fine. But on printful, only one of the product was there in the order created.

Some helpful info:

• User paid for both products (through Stripe)
• The cart data of that order had variant: 0 for the product that was skipped. However the data.json file of that product has correct variant ID set.
• Since variant: 0 was non-existing in the printful-ids.json for the product, it was filtered out here.
• The skipped product has no variants on Printful. Could be the reason why variant: 0 was set.

Unfortunately, I couldn't reproduce it on the shop using the same products and variants. Not sure if it has happened before either.
