Hello, @Wcn123,
Thank you for reaching out to our customer community. Welcome!
This error is usually triggered when an invalid value that does not match a field's format is provided (such as letters in a numerical field). Please make sure that all recently changed fields have valid values for their format when encountering this error. We also recommend checking that the attributes below are provided/correctly if the error persists:
first row of the item: Product Type, Item Name and language
DAM | Ecomm Header attribute set: Product Description, Brand Name
Weight and Dimensions attribute set: Gross Weight, Depth, Height, Width
Hierarchy Information attribute set: Total Count of All Products
Thank you
