QuickBooks found an error when parsing the provided XML text stream.

[hhuutan]

I'm trying to create a Sales Order but receive message: QuickBooks found an error when parsing the provided XML text stream.
This is my XML:

<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="13.0"?>
<QBXML>
  <QBXMLMsgsRq onError="stopOnError">
    <SalesOrderAddRq>
      <SalesOrderAdd defMacro="MACROTYPE">
        <SalesOrderLineAdd>
          <Rate>1.00</Rate>
          <ItemRef>
            <ListID>160000-933272656</ListID>
          </ItemRef>
          <Quantity>2.00</Quantity>
          <Amount>200.00</Amount>
        </SalesOrderLineAdd>
        <SalesOrderLineAdd>
          <Rate>1.00</Rate>
          <ItemRef>
            <ListID>1C0000-933272656</ListID>
          </ItemRef>
          <Quantity>2.00</Quantity>
          <Amount>200.00</Amount>
        </SalesOrderLineAdd>
        <CustomerRef>
          <ListID>800000DD-1702612106</ListID>
        </CustomerRef>
        <RefNumber>SO-001</RefNumber>
        <BillAddress>
          <Addr1>110 Main Street</Addr1>
          <Addr2>Suite 2000</Addr2>
          <State>TX</State>
          <PostalCode>99875</PostalCode>
          <Country>US</Country>
        </BillAddress>
        <DueDate>2019-10-10</DueDate>
      </SalesOrderAdd>
    </SalesOrderAddRq>
  </QBXMLMsgsRq>
</QBXML>

The reason is the order of fields is not match. For example, in your request the first tag should be CustomerRef, then RefNumber, after BillAddress etc. So here is a correct version of the request:

<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="13.0"?>
<QBXML>
  <QBXMLMsgsRq onError="stopOnError">
    <SalesOrderAddRq>
      <SalesOrderAdd defMacro="MACROTYPE">
       <CustomerRef>
          <ListID>800000DD-1702612106</ListID>
        </CustomerRef>
        <RefNumber>SO-001</RefNumber>
        <BillAddress>
          <Addr1>110 Main Street</Addr1>
          <Addr2>Suite 2000</Addr2>
          <State>TX</State>
          <PostalCode>99875</PostalCode>
          <Country>US</Country>
        </BillAddress>
        <DueDate>2019-10-10</DueDate>
        <SalesOrderLineAdd>
          <ItemRef>
            <ListID>160000-933272656</ListID>
          </ItemRef>
          <Quantity>2.00</Quantity>
          <Rate>1.00</Rate>
          <Amount>200.00</Amount>
        </SalesOrderLineAdd>
        <SalesOrderLineAdd>
          <ItemRef>
            <ListID>1C0000-933272656</ListID>
          </ItemRef>
          <Quantity>2.00</Quantity>
          <Rate>1.00</Rate>
          <Amount>200.00</Amount>
        </SalesOrderLineAdd>
      </SalesOrderAdd>
    </SalesOrderAddRq>
  </QBXMLMsgsRq>
</QBXML>

How to fix it in the code?

My latest commit lost the order of things. Let me see what I can do.

[jsgoupil]

Can you paste your code showing me how you make your request please?

[hhuutan]

My temporary solution is using [XmlElementAttribute(Order = ... )] above each public property in Objects class and it works well.
My code example:

/// <remarks/>
        [XmlElementAttribute(Order = 1)]
        public CustomerRef CustomerRef
        {
            get
            {
                return this.customerRefField;
            }
            set
            {
                this.customerRefField = value;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 2)]
        public ClassRef ClassRef
        {
            get
            {
                return this.classRefField;
            }
            set
            {
                this.classRefField = value;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 3)]
        public TemplateRef TemplateRef
        {
            get
            {
                return this.templateRefField;
            }
            set
            {
                this.templateRefField = value;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 4)]
        public DATETYPE TxnDate
        {
            get
            {
                return this.txnDateField;
            }
            set
            {
                this.txnDateField = value;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 5)]
        [System.ComponentModel.DataAnnotations.StringLength(11)]
        public string RefNumber
        {
            get
            {
                return this.refNumberField;
            }
            set
            {
                string temp = QbNormalizer.NormalizeString(value, 11);
                this.refNumberField = temp;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 6)]
        public BillAddress BillAddress
        {
            get
            {
                return this.billAddressField;
            }
            set
            {
                this.billAddressField = value;
            }
        }

        /// <remarks/>
        [XmlElementAttribute(Order = 7)]
        public ShipAddress ShipAddress
        {
            get
            {
                return this.shipAddressField;
            }
            set
            {
                this.shipAddressField = value;
            }
        }

[jsgoupil]

Can you please provide the code you use to make the request. The framework you use as well?

[jsgoupil]

I cannot repro the problem, so I need the code you used to make the problem happen. Not the solution.

[jsgoupil]

And tell me which framework you are using please...

[hhuutan]

I'm using .net core 2.2 in my web project

[hhuutan]

Hey, my lastest test in your sample was passed but in my project with .net core 2.2 was failed. This is probably the main reason. So sorry

[jsgoupil]

There is a problem with .NET Core 2.2
We will have to fix this.
