I am creating an endpoint that will make a request to a SOAP service with soap npm library. This is the imlementation I’m using.

import xml2js from "xml2js";

const soap = require('soap');
const wsdlPath = 'path_to_wsdl.wsdl';
const endPoint = endpoint_to_service;

const clientOptions = {
  disableCache: false,
  endpoint: endPoint,
  escapeXML: false,
  preserveWhitespace: true,
};

let soapClient = await soap.createClientAsync(wsdlPath, clientOptions);
//privateKey and cert are the variables containing my certificates for the service
soapClient.setSecurity(new soap.WSSecurityCert(privateKey, cert));
soapClient.addHttpHeader('Content-Type', 'application/soap+xml');

const builder = new xml2js.Builder({
  headless: true,
  rootName: "servicerequest",
});

//variable request being an object with the parameters for the service
const xml = builder.buildObject(request);
const result = (await soapClient.methodAsync({
  _xml: xml,
}));

The problem is when the code is executed, I get the following error

ERROR   Invoke Error

  "errorType": "TypeError",
  "errorMessage": "Converting circular structure to JSONn    --> starting at object with constructor 'ClientRequest'n    |     property 'socket' -> object with constructor 'TLSSocket'n    --- property '_httpMessage' closes the circle",

    "    at async /var/task/src/v1/functions/savePayment/index.js:8:923167"
  ]
}

I’m not sure where or why this error is coming up. I would appreciate for any insights on this issue
