Client opened session with ID 1 but the SOAP header targets session with ID 2!

Question

We are calling IDS from a nodejs app using the "node-soap" component. We are now introducing sessions and encountering the issue.

I just stared a session and tried to close it. Always get error message inside the event soapError saying "Client opened session with ID 1 but the SOAP header targets session with ID 2!" .If I try to run it again I get error "Client opened session with ID 1 but the SOAP header targets session with ID 3!". Tried runscript() also , It ran successfully but still get the error message.

I use indesign server 2015.

Please see the code which I use,

var soap = require("soap");

var url = "http://localhost:8194/wsdl?wsdl";

var args = { "IDSP:runScriptParameters":

{

"scriptLanguage": "javascript",

"scriptFile": scriptPath,

"IDSP:scriptArgs" : [

{ "IDSP:name" : "user",

"IDSP:value" : thisUser}

]

}

};

soap.createClient(url, function(err, client) {

client.on("soapError", function(err) {

console.log(err.message);

return errDataCallback(soapErr);

});

var sessionId;

client.BeginSession(function(err,session,test1){

sessionId = session.sessionID;

console.log("sessionID : "+sessionId);

if(err){

return errDataCallback(err);

}

var result = client.addSoapHeader({"sessionID":sessionId},"sessionID","IDSP","");

var sessionArg = { "IDSP:sessionID": sessionId.toString()};

client.EndSession(sessionArg, function(err){

console.log(err.message);

});

Please help me to resolve the issue.

Ok I finally figure it out.The issue is that IDS attach in some way a socket to a session.So whenever the socket is closed, the session is closed as well.The trick in nodejs is to create a custom http.Agent you pass to your http request for each session you want to be maintained with (for example) those params :let keepAliveAgent = new http.Agent({            keepAlive: true, // so the socket is not closed after http request completion (do not forget to do a request.end() after your request.write())            keepAliveMsecs:600000, // set to enough time to not have the connection timed out            maxSockets:1 // ensure that the Agent does not open an other parralell socket        });Then for each http request you create to be executed within the session (including the beginSession and endSession) you pass that Agent as parameter :RequestOptions = {            hostname: server.hostname,            port: server.port,            path: server.path,            method: 'POST',            headers: {                'Content-Type': 'text/xml;charset=UTF-8',                'Content-Length': Buffer.byteLength(postData),                'Connection': 'Keep-Alive',                'SOAPAction':'""'            },            agent:keepAliveAgent} For any new session, you just create a new http.Agent ...
