You probably missing ConversionSchema set for DynamoDBMapperConfig. Try:
DynamoDBMapperConfig.builder().withConversionSchema(ConversionSchemas.V2_COMPATIBLE).
I faced exactly the same issue after changing builder from new DynamoDBMapperConfig.Builder() to DynamoDBMapperConfig.builder() <- the last one does not set defaults.
