Let's say this one:
https://zavod.crm-onebox.com/admin/shop/storage/passport/3324/edit/This is just a test product, blank. But with real ones, it's easy to recreate the bug:
1. Create a product passport
2. We launch some bp, where the specified product appears in the table of products
3. Delete the bp (the product is still hanging in the product table)
4. We go to the passports and try to delete the product passport - an error pops up
In this case, it is enough to go to the bp that will be indicated in the error and delete the product from the table (you don’t even need to save / restore the deleted bp) and the passport can be deleted.
