Date Time and Debug not correct

Hagashen Naidu 1 year ago in Server / Execution 0

Please see attached workflow. When passing the following JSON as input:

"dateTime": "2020-04-14T09:20:18.982Z"

Even though the JSON is valid and I have specified the DateTime Input Format correctly when I debug I get an error that the Input String is not in the correct format. However when I 'View in Browser' it does not show an error. Furthermore the debug input of the tool does not show the input due to the error.


Date Time Issue.bite

PS. I got this to work by making the input format my current system format as it turned out, internally the Newtonsoft de-serializer interprets the DateTime into the system format. This is however hidden from user and would be difficult to find.

I think showing the Debug Input values would help the user see what value was actually being used and then they could adjust the format based on that. There is a case for saying that the format should not have changed without me explicitly doing so.

RabbitMQ limitations (messages per second)?

Michael 3 years ago in Server / Execution 0


is there any limitation on the RabbitMQ Publish Module? 

In my case, I have one recordset with about 60000 different numbers. Now I want to publish this to RabbitMQ. But I only got a message rate of max. 20/s. That's not so fast. With other tools I reached over 20000 per second. 

During the job runs, I've checked the system performance. 
CPU: < 25%

RAM:  2,5Gb / 8Gb

How much messages can WareWolf send to RabbitMQ?

Executing javascript (question and ideas)

playsted 5 years ago in Server / Execution updated by Pieter 5 years ago 6

What javascript execution engine is used? I have having issues with scripts as some functions are not working properly.

Problem 1:


is valid javascript and works with node and browsers. This should return true.

However running this as a script in a workflow results in an error due to it not being a function.

Problem 2:

If I use variables in the script the strings are not escaped.


[[testPath]] = "C:\test"

In script:

"[[testPath]]" => "c:est"


I think it would be very powerful to use node.js as the javascript execution as it is so widely used. Edge.js is a c# library that allows node to easily be executed from .Net. I haven't researched it much but may be an option.

As far as escaping strings you could predefine them all on a javascript object that the script runs in. Instead of using [[varName]] we could just use $ww.varName if we use $ww as the example object that Warewolf populates. This would take care of string escaping problems and even allow complex objects to be manipulated as expected while coding javascript.

Hi Playsted,

We will look into updating the library in a coming version.

Thanks for the suggestion and thinking on this we will definitely consider it.


Workflow Persistence

playsted 5 years ago in Server / Execution updated by Genie 5 years ago 1


Is workflow state persisted? Can long running workflows (for example if waiting for user interaction/approval) be resumed on server restart? I know workflow foundation supports this (if enabled) but didn't see any specifics in documentation.

Hi Playsted,

We have moved away from using the Workflow Foundation engine and in doing so we did not have an immediate requirement from any of our customers to support workflow persistence, and so we did not implement it. So at present there is no state persistence in Warewolf, however should the requirement arise in the market then we can implement it.

HTTPS connection from localhost to a remote server

keith_k 5 years ago in Server updated by Gandalf 5 years ago 3

How do you add an SSL certificate or what is needed to make an HTTPS connection to a web server?

When I click New Remote Server, I am able to successfully connect to my remote server with http://ipaddress:3142 as the address and Microsoft User/Password authentication. However, I receive the following error when trying to connect with https://ipaddress:3143

Connection Error : An error occurred while sending the request.


My remote server is a VM through Microsoft Azure. The VM was created with the Warewolf ESB, so the HTTP: TCP/3142 and HTTPS: TCP/3143 inbound security rules are all in place. Also, I can successfully connect to my localhost machine from the remote server with both HTTP/HTTPS.

File already exists

When trying to write a file, I keep getting the error: File already exists.

This was working before as the tool is set to overwrite and nothing has changed, it just stopped working.

Format Number tool giving error on valid numbers!

Kyle TFL 6 years ago in Server / Execution updated by Gandalf 6 years ago 3


Im passing a recordset of numbers into the Format Number tool and I keep getting an error in the debug: One of the identified items was in an invalid format.

Everything works until I start passing in decimal numbers, regardless of if I try and round them or not.

I have checked my computer regional settings and they are correct for the numbers I am using e.g. 200.0876 and regional settings says use a full stop . for Decimal Symbol.

I dont know what else to do, please help.

WCF Host/Endpoint Support

Victor Rocha 6 years ago in Server / Resources updated by Genie 5 years ago 7

Are you planning to support (host) WCF services?

I mean, give to user the ability to load a DLL dynamically and host it (endpoint) within Warewolf ESB to be accessed by Warewolf and any other WCF client? Is it possible?


  • 1 - Load DLL - WCFHelloService.IHelloServiceBus - (Contract - mapping methods dynamically)

  • 2 - Host it:
using System.ServiceModel;
ServiceHost host = new ServiceHost(typeof(HelloServiceBus), uri);

  • 3 - Turns it available as a WCF's endpoint (Some binding types) to be consumed by any WCF client and Warewolf ESB:

<service name="WCFHelloService.HelloServiceBus">
<endpoint address="net.tcp://warewolfendpoint/HelloService" binding="netTcpBinding" contract="WCFHelloService.IHelloServiceBus"/>
I believe, if it is possible, that WCF hosting will give much more integration capabilities, enabling users to concentrate all its WCF services into Warewolf ESB.
Best regards!

Hi Victor,

Warewolf ESB currently allows connecting to webservices as well as loading of .net dll so both these methods are options to access an existing WCF service.



Executing Warewolf service in javascript

Henry Jones 7 years ago in Server / Execution updated by Gandalf 7 years ago 3

I saw the example for executing a warewolf service using Javascript in the examples folder. However i tried doing it using jQuery as so

<script type="text/javascript">
function execution() {
var wareWolfUrl = "http://localhost:3142/services/Hello World.json

type: "GET",
url: wareWolfUrl,
cache: false,

success: function (response) {
error: function (errorThrown) {
complete: function (e) {

i am getting the following error:

XMLHttpRequest cannot load http://localhost:3142/services/Hello%20World.json? No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:23128' is therefore not allowed a... response had HTTP status code 401.

Am i doing something wrong or is the way in the sample the only way that the service can be executed.
