How do I fix " BIZ_CHECK_PROP_REQUIRED:100006619size This sales property is required." from Lazada?
On July 2025, Lazada started adding mandatory options to variants based on the Lazada Category. This error is saying that you need to have "size" option on your variants. You can fix this by:
- if you are syncing variants with the app: adding a new size option on Shopify, or
- if you are NOT syncing variants with the app: adding the size option on Lazada Seller Center
- changing the Lazada category for this product, from the Lazada Seller Center
