Unmarshall JSON Response from DynamoDB

[bannostookaylo]

Is there a way with boto3 to unmarshall a json response from querying dyanmodb? I want to avoid having to import another module like https://pypi.org/project/dynamodb-json/

While we do have an abstraction for this. This class is considered internal so there is a chance that it subjected to breaking changes in the future. Otherwise marking this as a feature request to publicly expose our DynamoDB marshallers/unmarshallers.

Any updates on whether this functionality has been made public?

I don't understand why this is taking so long to expose. After all the other language SDK's have this functionality exposed

I actually came across this issue as well. I was never able to get the TypeDeserializer to work correctly. I ended up rewriting my logic to take advantage of the Table Resource in dynamodb. Only way I was able to get my API to return the results correctly. Idk if that helps or not. Just throwing it out there.

TypeSerializer and TypeDeserializer are documented here: https://boto3.amazonaws.com/v1/documentation/api/latest/_modules/boto3/dynamodb/types.html

I think this example is what was requested but this comment mentioned earlier still stands:
