Unmarshalling DynamoDB streams event: events.DynamoDBAttributeValue

[kaihendry]

Describe the issue with documentation

cannot use record.OldImage (variable of type map[string]events.DynamoDBAttributeValue) as map[string]"github.com/aws/aws-sdk-go-v2/service/dynamodb/types".AttributeValue value in argument to attributevalue.UnmarshalMap

Suggestion

https://aws.github.io/aws-sdk-go-v2/docs/code-examples/dynamodb/ is very light.

We need some serious examples, like saving removed dynamodb Items via DynamoDB streams.

I am puzzled how to unmarshal https://pkg.go.dev/github.com/aws/[email protected]/events?utm_source=gopls#DynamoDBStreamRecord.OldImage using https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/feature/dynamodb/[email protected]?utm_source=gopls#UnmarshalMap ... are they not effectively the same?

• https://pkg.go.dev/github.com/aws/[email protected]/events?utm_source=gopls#DynamoDBAttributeValue
• https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/service/dynamodb/types#AttributeValue

I'm very confused.

AWS Go SDK version used

v1.23.0
