Node.js, AWS Lambda - Consume a SOAP service that requires WS-Addressing and v1.2 specification using node-soap module

consume-soap.js

var soap = require('soap');

var url = 'http://example.org/MyWebService.svc?wsdl';

var soapOptions = {
    forceSoap12Headers: true
};

var soapHeader = {
    'wsa:Action': 'http://tempuri.org/MyBinding/MyOperation', 
    'wsa:To': 'http://examle.org/MyWebService.svc'
};

exports.handler = function(event, context, callback) {
    var params = {
        param1: event.param1,
        param2: event.param2
    };

    soap.createClient(url, soapOptions, function(err, client) {
        if (err) callback(err);
        client.addSoapHeader(soapHeader, '', 'wsa', 'http://www.w3.org/2005/08/addressing');
        client.MyOperation(params, function(err, data) {
            if (err) callback(err);
            callback(null, data);
        });
    });
}

Did you at any point have issues with soap rejecting the URL parameter? I've been getting a header contains invalid character (empty soapOptions as not using 1.2) ~ only in lambda. Soap wrapper works fine elsewhere

Sorry for my late reply. I haven't been using Node.js and AWS Lambda for a long time. However, I didn't encounter such an error, as far as I can remember.
