I have the following code to execute a SOAP request with an wsse header but it seems not to work. I get a error response but I am not able to get the fault/error out of the response.

Does the below code look correct or do I miss something?

var request = "<soapenv:Envelope" +
    "xmlns:dlg='http://dlg123Lib'" +
    "xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'>" +
    "<soapenv:Header>" +
        "<wsse:Security" +
            "xmlns:wsse='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'" +
            "xmlns:wsu='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'>" +
            "<wsse:UsernameToken wsu:Id='UsernameToken-BF09AFF37A2C36D4AB164000000000000000'>" +
                "<wsse:Username>BLABLABLA</wsse:Username>" +
                "<wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>BLABLABLA</wsse:Password>" +
            "</wsse:UsernameToken>" +
        "</wsse:Security>" +
    "</soapenv:Header>" +
    "<soapenv:Body>" +
        "<dlg:getData>" +
            "<name>AB</name>" +
        "</dlg:getData>" +
    "</soapenv:Body>" +
"</soapenv:Envelope>"

jQuery.ajax({
        url: 'https://endpoint_url/dlg/data',
        type: "POST",
        data: request,
        dataType: "xml",
        contentType: "text/xml; charset='utf-8'",
        success: function (soapResponse) {
            alert("Success");
        },
        error: function (soapResponse) {
            alert("Error");
        }
});

When I execute the exact same request like above in SoapUI without setting an Authorization the request is executed correctly.

So it must be something wrong with the jQuery implementation(?)

UPDATE 15.01.2022 I was told by the customer that the Payload of the request is empty. Anybody an idea why this could happen?
