["[Code:5000] [Error]XML Parsing Error at Line 1, Column 3141: cvc-minLength-valid: Value 'AC0592' with length = '_' is not facet-valid with respect to minLength '8' for type '#AnonType_ValueStandardProductID'.","[Code:5000] [Error]XML Parsing Error at Line 1, Column 3141: cvc-type.3.1.3: The value '______' of element 'Value' is not valid."]

Reason: If the above error gets returned, it is indicating that the value you put in for your Standard Product ID is under the minimum 8 characters. The Standard Product ID can refer to GTIN, UPC, etc. It's important to note if you are using UPCs, then the minimum length is 12 characters. 

Solution: Entering a valid standard product ID that is at least 8 characters (except for UPC) should resolve this issue
