Hello, you have indicated a specific product.id from our product catalog, so in this case, we do not pay attention to the parameters section - we try to list an offer with the product data that we have in our catalog. This product does not have GTIN included, that is why we returned an error.

You can suggest to add GTIN to this product via website - https://salescenter.allegro.com/changes-in-product-catalogue/report/6eef92b4-943b-4471-89bd-5e24ed38a26b or using API.
