Hi there,

In the past we used to be able to call the ErPServiceCaller directly from a test connector. However, when I do that now on DW 9, I get this:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Dynamicweb.Core.SystemInformation.GetBasePath(String& relativePath)
   at Dynamicweb.Core.SystemInformation.MapPath(String relativePath)
   at Dynamicweb.Configuration.SystemConfiguration.get_Instance()
   at Dynamicweb.DataIntegration.Integration.ERPIntegration.ErpServiceCaller.GetBinding(String endpoint, TimeSpan timeout)
   at Dynamicweb.DataIntegration.Integration.ERPIntegration.ErpServiceCaller.GetDataFromRequestString(String endpoint, String secret, String requestXML)
   at TestConnectors.DWConnectorTest.ProcessRequest(String request)
   at DynamicwebServiceTester.TesterControl.ExecuteTest()

It's crashing on getting a path in SystemInformation

Does that happen because I am not in a web app? Or is there something wrong in SystemInformation?

Imar

It happens because it tries to read a timeout setting from global settings, but the system has not yet been initialized, which is usually handled when the web application starts up (GlobalAsaxHandler).

As a workaround you can try to set the root directory like this:

SystemInformation.RootDirectory = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory)

Thanks Morten, I'll give that a try!
