An unexpected error occurred while creating contact record

Hello All,

We are experiencing a strange error in the below mentioned code

var record = new Contact
{

FirstName = DataGenerator.RandomName(),
LastName = DataGenerator.RandomName(),
BirthDate = birthdate.AddDays(1),

Custom_Attribute1= XXXXX

}

var createRequest = new CreateRequest
{
Target = record,
};

record.Id = ((CreateResponse)context.OrganizationService.Execute(createRequest)).id;

The error occurrs intermittently and it is

An unexpected error occurred. NullReferenceException

at the above highlighted line, some time the record is created without any error.

Is this because some of the attributes missing when creating the record?

We are using Dynamics 365 on premise Version 1612 (8.2.28.11) (DB 8.2.28.11) on-premises.

There are some plugins on OnCreate Pre and Post Operation of the Contact, and the aove mentioned code is in the Web API which is used by some application.

If anyone has some inputs with such similar issue, please let me know.

Regards,

Abhi.

Hi,

Please check Plugin trace log if any error logged due to your custom plugin on Contact Entity.

I believe error is coming from your custom sync plugin. Otherwise your code looks good to me.

Also, please change your last line of code as below -

var response = ((CreateResponse)context.OrganizationService.Execute(createRequest));

record.Id = response.id;

Please mark my answer verified if this is helpful!

Hi Abhi,

Here is an example of using CreateRequest with IOrganizationService.Execute.

CreateRequest request = new CreateRequest() { Target = account }; var id = ((CreateResponse)svc.Execute(request)).id;
