I want to create a contact in Dynamics 365 from a webpage but I'm getting a basic error which tells me nothing.
Exception rethrown at [0]

Please help.

 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
        Dim service As CrmServiceClient = New CrmServiceClient(ConfigurationManager.ConnectionStrings("CRM").ConnectionString)
        Dim contact As Entity = New Entity("contact")
        Dim lang As String = "7ed34d80-5755-e511-80e9-3863bb34ea78" ' us english
        Dim langGuid As Guid = New Guid(lang)


        contact("firstname") = "Stuie"
        contact("lastname") = "Green"
        contact("emailaddress1") = "stuapitest@xxx.com"
        contact("tri_sitelanguageid") = langGuid
        contact("tri_al_atpcampaign") = "test Form"
        contact("tri_al_country") = "USA"
        contact("tri_al_enquiry") = "testing"
        contact("new_testid") = langGuid

        Try
            service.Create(contact)
        Catch ex As Exception
            Response.Write(ex.Message)
            Response.End()
        End Try

Hi,

Instead of using Exception class, I will suggest you to catch OrganizationServiceFault which will give you error details

msdn.microsoft.com/.../gg327884.aspx

it looks that tri_sitelanguageid and new_testid are lookup fields so you need to setup these fields values using following snippet:

contact("tri_sitelanguageid") = new EntityReference(<EntityLogicalName>, langGuid)

contact("new_testid") = new EntityReference(<EntityLogicalName>, langGuid)

Hi all

I got this to work OK and its now creating contacts fine BUT I have another plugin in CRM that updates a SQLdb when modified date changes.

It appears that when a new contact is created, this step message of Update triggers the plugin and causes the error.
I think its probably trying to update a record that's not been created yet in SQLdb

How can I see error details like i can when using profiling of the plugin.

All i see on the webpage is

Unexpected exception from plug-in (Execute): ContactDataProcessing.GetContactDataPlugin: System.NullReferenceException: Object reference not set to an instance of an object.

You can control update plugin using filtering attribute to only trigger your update plugin on change of specific fields, docs.microsoft.com/.../include-filtering-attributes-plugin-registration

further if you want to debug your plugin you can check my post here: http://himbap.com/blog/?p=2469

Thanks Mahener. Id like to use filtering.

I already have modifiedon as a filter but can I add logic to say only run the plugin if modifiedon != createdon

Also the debugging only seems to be for when I have a profile file to test against. I'm running an aspx page to call the plugin so don't have a profile
