Excluding one Entry property in DBUpdateException from log in NLog

Question

I have an entity with byte[] property, when DBUpdateException occurs it pours it into a json log, since DbUpdateException contains Entries list, which includes every single entry's\entity property. I wonder if there is a way to prevent this one property to be logged. I'm using NLog 5.2.5 (JsonLayout), EF Core 5.

You can override the property-relection for an object-type like this:

LogManager.Setup().SetupSerialization(s =>
   s.RegisterObjectTransformation<DBUpdateException>(ex => new {
      Type = ex.GetType().ToString(),
      Message = ex.Message,
      StackTrace = ex.StackTrace,
      Source = ex.Source,
      Data = ex.Data,
      InnerException = ex.InnerException,
   })
);
