The AttributesToGet is legacy. ProjectionExpression is the correct way to fetch the columns.

When changing this, add support for checking against reserved keywords, and escaping them if found. Otherwise an "InvalidXExpression: Attribute name is a reserved keyword; reserved keyword: " exception will be thrown.

...
ProjectionExpression: "AlbumTitle, #y",
ExpressionAttributeNames: {"#y": "Year"}

Reserved words in DynamoDB
