Create product variants using GraphQl API documentation (2024-10). Error occurred while creating variant,Tip: Variable $variants of type [ProductVariantsBulkInput!]!, I referred to the documentation and discussion forum, but did not find the problem. I hope this issue can be resolved in the forum. Thank you very much!
