How can I make Soap api call from node js using soap npm

I tried to use "soap" npm and build an object to be sent as param but the object is not able to be converted to envelope. I posted the file and response below app.js file contain the below

            var soap = require('soap');
            const express = require('express');
            const bodyParser = require('body-parser');
            
            var app = express();
            app.use(bodyParser.json());
            const url = 'https://files.developer.sabre.com/wsdl/sabreXML1.0.00/shopping/SSSAdvShopRQ_v5-4-0.wsdl';
            
            let params = {
                Envelope: {
                    Header: {
                        Action:"SSSAdvShopRQ",

                    console.log(response.data);
                    res.setHeader('Content-Type', 'application/json');
                    res.status(200).send(response.data);

                console.log("Server started at port 3000");
            });

I get the below response

soap-env:Fault soap-env:Client.InvalidEbXmlMessage Missing <soap-env:Header> in <soap-env:Envelope> javax.xml.soap.SOAPException: Missing <soap-env:Header> in <soap-env:Envelope> </soap-env:Fault>

I am looking how to convert from object to request envelope.

I have no token and username/password. I can't test this API.

But I can suggest your try this steps.

#1 Find correct input data parameters before node.js call using soapUI.

This is detail information for using simple calculator.

Example: You need to enter this values

<sec:Username>your user name</sec:Username>
<sec:Password>your user password</sec:Password>
<sec:BinarySecurityToken>real binary token</sec:BinarySecurityToken>

#2 Then resume node.js without express

This is detail information for soap-npm node.js.

In I found more easy way to consume SOAP service section.

#3 With express
