AWS DynamoDB创建本地二级索引

Question

我正在创建一个包含本地二级索引的dynamoDB表。如果我在下面的语句中运行，它可以正常工作。

aws dynamodb create-table                        \
    --table-name XYZ                             \
    --attribute-definitions                      \
        AttributeName=Id,AttributeType=N         \
        AttributeName=Name,AttributeType=S       \
    --key-schema                                 \
        AttributeName=Id,KeyType=HASH            \
        AttributeName=Name,KeyType=RANGE         \
    --provisioned-throughput                     \
        ReadCapacityUnits=5,WriteCapacityUnits=5 \
    --local-secondary-indexes                    \
        'IndexName=idx1,
         KeySchema=[{AttributeName=Id,KeyType=HASH},{AttributeName=Name,KeyType=RANGE}],
         Projection={ProjectionType=ALL}'

但是，如果我尝试使用以下语句添加其他属性：

aws dynamodb create-table                        \
    --table-name XYZ                             \
    --attribute-definitions                      \
        AttributeName=Id,AttributeType=N         \
        AttributeName=Name,AttributeType=S       \
        AttributeName=Gender,AttributeType=S     \
    --key-schema                                 \
        AttributeName=Id,KeyType=HASH            \
        AttributeName=Name,KeyType=RANGE         \
    --provisioned-throughput                     \
        ReadCapacityUnits=5,WriteCapacityUnits=5 \
    --local-secondary-indexes                    \
        'IndexName=idx1,
         KeySchema=[{AttributeName=Id,KeyType=HASH},{AttributeName=Name,KeyType=RANGE}],
         Projection={ProjectionType=ALL}'

我收到以下错误消息：

when calling the CreateTable operation: One or more parameter values 
were invalid: Some AttributeDefinitions are not used. 
AttributeDefinitions: [Id, Name, Gender], keys used: [Id, Name]

有关如何解决问题的任何建议。
