Could not marshalled the object

[dishant2612]

Hello,

1. I created INVOICE.js in mappings folder using below command
   java -jar \lib\jsonix-schema-compiler-full-2.3.9.jar -d mappings -p INVOICE https://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/maindoc/UBL-Invoice-2.1.xsd

2. Then tried to marshalling the object to XML and getting below error
   Error: Element [xsd:schema] is not known in this context, could not determine its type.

Here is the snippet

let xmlData = marshaller.marshalDocument({
    name: {
        localPart: "Invoice"
    },
    value: {
        "cac:InvoicePeriod": {
            "cbc:StartDate": "2009-11-01",
            "cbc:EndDate": "2009-11-30",
        }
    }
});

Any help will be highly appreciated. Thanks

PS: code jsonixInvoice for reference
