Add nullable property type support for dynamodb. #337

Closed AmirHJabari closed 2 years ago

AmirHJabari commented 2 years ago

The DynamoDb provider wasn't able to predict Nullalbe<T> types. For example it was saving a DateTime? property like 17/03/2022 00:00:00, (default one) which calls 

Value.ToStringOrEmpty()

not

 ((DateTime)Value).ToString("yyyy-MM-dd'T'HH:mm:ss.fff'Z'")

The ERROR:

System.InvalidOperationException: Unable to convert [17/03/2022 00:00:00] of type Amazon.DynamoDBv2.DocumentModel.Primitive to System.Nullable`1[[System.DateTime, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]
