Error: DynamoDB Not Supported Requires @DynamoDBTyped Or @DynamoDBTypeConverted

What's Causing This Error

DynamoDB only supports several data types, and sometimes it does not understand how to handle your complex data types. So, in such instances, if you do not define a converter class to specify how to convert your object to a string and back again, DynamoDB will throw this error.

Solution: Here's How To Resolve It

To resolve this error, you have to check and verify that all the values passed are properly annotated. You can also use DynamoDBMapper to handle the conversions between the data types automatically.
