@Andrew_Lewis,

Can you show what BaseDataClass looks like? The problem is most likely in this class.

Alexander

Hi Alex.

I have tried with both the following:

using System;

namespace Shared.Core
{
public class BaseDataClass
{
public string objectId { get; set; }
public string ownerId { get; set; }
public DateTime created { get; set; }
public DateTime updated { get; set; }
public string recordType { get; set; }
public bool CanBeDeleted { get; set; }
public bool Global { get; set; }
}
}

using System;

namespace Shared.Core
{
public class BaseDataClass
{
public string objectId { get; set; }
public string ownerId { get; set; }
public string recordType { get; set; }
public bool CanBeDeleted { get; set; }
public bool Global { get; set; }
}
}

Hi Andrew,

What is the version of the Backendless SDK for .NET you use?

Hi @Andrew_Lewis

Please try replacing DateTime with DateTime?
The value you are sending is not null and replaces the real value

Alexander

Hi, I’m using Backendless.NET 6.2.0.

Replace DateTime with DateTime?

@Andrew_Lewis DateTime to DateTime?
Add a question mark to the name of the data type.

Regards, Nikita.
