如何从Athena中查询DynamoDB嵌套元素

【以下的问题经过翻译处理】 我正在尝试在DynamoDB文档中提供的示例电影表上执行查询。我尝试了以下几种变体，但结果都是相同的语法错误。

可以在以下网址上找到数据样本： https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GettingStarted.Python.02.html

以下是Athena查询和输出。具体错误是：“无法解析列'lds。”info“。”release_date“'”

bash$ aws athena start-query-execution --query-string "select lds.\"info\".\"release_date\" from \"dynamodb\".\"default\".\"movies\" as lds where year = 1985" --region us-east-1 --work-group AmazonAthenaPreviewFunctionality
{
    "QueryExecutionId": "f1c21259-43ea-4c69-8c42-55ff70998953"
