If you encountered the error "An order's weight information is mandatory. You need to add weight information to every product variant you want to ship.", a product variant in the order is likely missing its weight.
Quick fix for this order:
Export the affected order via CSV. Follow the steps outlined in this tutorial for CSV export.
Open the parcel in your Packeta account under Unfinished Parcels.
Add the missing weight manually, then save and submit the parcel.
Print the label from the Posted Parcels section.
Then make sure to also fix the weight in Shopify so the issue doesn't repeat on future orders — follow the steps below.
Check if you added weight to every product variant
Zasilkovna / Packeta requires sending order weight with every parcel imported to their system via either API or CSV.
To ensure this, the Zasilkovna app sums all the product variant weights in order and sends the information to the Zasilkovna admin.
The most common issue is that the weight was added only to one variant per product, thinking that the weight stands for all the variants within one product, but Shopify needs to have weight for every variant.
