Object reference not set to an instance of an object.

Posted on by Community Member Microsoft Employee

Dear All,

I'm trying to insert couple of records for Entity person 

here is the code I wrote:

Entity account  = new Entity("contact");

            account.Attributes["firstname"] = "Test";

            account.Attributes["lastname"] = "Test";

            account.Attributes["datatel_prospectsourceid"] = "Beacardinal Website";

            account.Attributes["preferredcontactmethodcode"] = new OptionSetValue(2);

            account.Attributes["address1_telephone1"] = "3333333333";

But I keep getting this error message: "Object reference not set to an instance of an object." .

Any suggestions?

Regards

    RE: Object reference not set to an instance of an object.

    You are having this issue because of error with connecting to Dynamics 365. You can enable tracing for XrmTooling, like described here:

    docs.microsoft.com/.../configure-tracing-xrm-tooling

    In trace you should get more detailed information why you cannot connect (9 out of 10 times it's because you have bad connection string)

    RE: Object reference not set to an instance of an object.

    Well you are now providing string from code, so I can't tell you that. It depends from where you have this information. You are now setting "Beacardinal Website" which is hardcoded, so I can't see any difference in providing hardcoded Guid. Of course it would be better to put in some kind of configuration dictionary in CRM or whatever, but this is another story.

    RE: Object reference not set to an instance of an object.

    Thx fo the answer,

    There is a field for states and it's look up , so is there better way to just provide state value and it get guid instead of providing guid from code ?

    Thx alot

    RE: Object reference not set to an instance of an object.

    Hi,

    The problem is not CRM related, it's C# related. This code:

    using (var serviceProxy = new OrganizationServiceProxy(config, credentials))
           {
               // This statement is required to enable early-bound type support.
               serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
               service = serviceProxy;
               var who = new WhoAmIRequest();
               //retreive user data from the server.
               var whoResponse = (WhoAmIResponse)service.Execute(who);
               System.Diagnostics.Debug.WriteLine(whoResponse.UserId);
               return service;
           }


    makes no sense. You are creating serviceProxy in using {} block so it will be disposed when you exit using block. So returning this service makes no sense, you will be then trying to call a disposed object.

    If you want to use Using statement, you should wrap it around code that is using your service, so remove Using from CRMService method and do the Using statement inside submitInoRequestFormDataToCRM method.

    Also I'm not sure if this line is correct:

     account.Attributes["datatel_prospectsourceid"] = "Beacardinal Website";

    usually when the field is called like that it is EntityReference and you are assigning String to it. Assign EntityReference instead.

    Hi Mohammed,

    In order to set the lookup you need to use EntityReference. Below please find the sample for lookup to contact. The field is primarycontactid.

    EntityReference primaryContactId = new EntityReference("contact", contactId);

    account["primarycontactid"] = primaryContactId;

    Hi mohammed,

    It should be something like below.

    account.Attributes["originsource"] = new EntityReference("source", sourceId);

    Where:

    originsource = Name of the lookup

    source = Entity name of the Source entity

    sourceId = GUID of the Source record you are associating with contact.

    Hi mohammed,

    As Pawel mentioned, please provide the StackTrace.

    I noticed the first line is a bit strange.

    Entity account  = new Entity("contact");

    Which entity are you using? Account or Contact?  If it's Account record you are creating, change the code as below.

    Entity account  = new Entity("account");

    Also double check the attribute names you are using.  Maybe you have a typo.  Comment out the below three lines temporarily and just leave the mandatory fields and see if it works.

    account.Attributes["datatel_prospectsourceid"] = "Beacardinal Website";

    account.Attributes["preferredcontactmethodcode"] = new OptionSetValue(2);

    account.Attributes["address1_telephone1"] = "3333333333";
