You might be lacking a GTIN in your packaging node or it might be too early to be generated.
1) Have you added a GTIN to your packaging node?
Please check if you have added a GTIN in your packaging node as it is essential for creating the report. You can add the GTIN in a packaging node, and it should be added after all refinement steps.
If a refinement- or packaging step is added later on in the product chain in the same canvas or another downstream canvas, the GTIN will have to be added again later in the product chain.
If you have not added a GTIN previously, please send your canvases in for review again before publishing.
2) Is it too early?
