I’m receiving the following error on the 2nd action of the “SENDHTTPPOST Workflow Application” demo application that i downloaded from the github link ([https://github.com/advantys/workflowgen-templates/tree/master/integration/webhooks/sendhttppost](https://github.com/advantys/workflowgen-templates/tree/master/integration/webhooks/sendhttppost))

CODE: ErrorWebServiceCall (#217)  
SOURCE: WebServiceExecute  
MESSAGE: Error while invoking the web method Send : Exception has been thrown by the target of an invocation. : System.Web.Services.Protocols.SoapException: ‘Advantys.Workflow.Applications.SendHttpPost.SendHttpPost’ does not contain a definition for 'CreateDictionaryFromStringKeys’  
at Advantys.Workflow.Applications.SendHttpPost.SendHttpPost.Send(String WFGEN\_CONTEXT)

I believe i performed all the requirements correctly and followed the instructions. Can you please provide me some direction as to what this error means?

Hi,

I re-tested both .NET examples using JSON and URLENCODED content types in my WorkflowGen v7.1.1 and got no error; the application works as expected.  
I suggest you to post a ticket to our support team specifying your versions of WorkflowGen and [WorkflowGen.My](http://WorkflowGen.My) library, and we’ll try to resolve your issue.
