Table model

public class ExModel
{
  public int ID {get;set;}
  public string Name {get;set;}
  public decimal? TotalExpenses {get;set;}
}
Microsoft.EntityFrameworkCore.DbUpdateException: An error occurred while updating the entries. See the inner exception for details.

I'm not sure this error is happen from this lib or Cassandra driver.
