I apologize in advance for this poorly worded question.

I'm re-writing an older E2E test that performs a POST of an XML document to an internal site using vbScript. With WinHttpRequest and Microsoft.XMLDOM the data is accepted and appears as expected in the website. However, when I perform the "same" operation using Cypress I obtain different results.

My question: Is there difference in the way these two technologies perform the POST operation or am I missing something in the Cypress code?

Thanks in advance for any advice!

VBS

Dim xmlhttp, oXML
Set xmlhttp = CreateObject("Microsoft.XMLHTTP")
xmlhttp.open "POST", "https://InternalWebSite.com/Orders/CXMLOrder.aspx", False
xmlhttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded; charset=UTF-8"
xmlhttp.setRequestHeader "Content-length", "1000"
xmlhttp.setRequestHeader "Connection", "close"
xmlhttp.setRequestHeader "soapAction", ""
Set oXML = CreateObject("Microsoft.XMLDOM")
oXML.async = False
oXML.load(localPath & "\MyOrderFile.xml")
xmlhttp.send(oXML)

CYPRESS

it('Post Order File to Site', () => {
    const myOrderFile = 'C:\\Automation\\MyOrderFile.xml'
    cy
        .readFile(myOrderFile)
        .then(function (text) {
            cy.log(text)
            postXML(text)
         })
    })

function postXML(text) {
    return cy.request({ 
        url: 'https://InternalWebSite.com/Orders/CXMLOrder.aspx',
        method: 'POST',
        body: text,
        headers: {
            'content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
            'content-length': '1000',
            'connection': 'close',
            'soapAction': ''
        }
    }
)}
