Getting the Exception

var result = dbContext.SaveChangesAsync();
if (result.IsFailure(out var error))
{
    var ex = (Exception)error.Metadata["Exception"];
    // Do something with the base exception type or...
    
    if (ex is DbUpdateException dbUpdateException)
    {
        // Do something with a specific exception type
    }
}
