Question

使用javascript aws sdk

我的表定义如下：

  resources:
  Resources:
    ImagesTable:
      Type: "AWS::DynamoDB::Table"
      Properties:
        AttributeDefinitions:
          - AttributeName: "deviceId"
            AttributeType: "S"
          - AttributeName: "timeStamp"
            AttributeType: "N"
        KeySchema:
          - AttributeName: "deviceId"
            KeyType: "HASH"
          - AttributeName: "timeStamp"
            KeyType: "RANGE"
        ProvisionedThroughput:
          ReadCapacityUnits: 1
          WriteCapacityUnits: 1
        TableName: ${self:custom.settings.${self:custom.myStage}.ITEMS_DYNAMODB_TABLE}
        StreamSpecification:
          StreamViewType: NEW_IMAGE

我尝试运行查询并获取所有与字符串匹配的设备。

我的params对象是

        const params: DynamoDB.DocumentClient.GetItemInput = {
          TableName: eventLogTable,
          Key: {deviceId: 'device12345'}
        };

我的电话是

return this.client.get(params).promise()
        .then(result => {
            return result;
        });

在日志文件中，我看到以下错误：

2019-06-21T17:23:27.878Z    cc865442-8604-4f5c-8099-72eba87d9b2b    query params right before going in { TableName: 'sls-basic-operations-items-dev',
Key: { deviceId: 'device12345' } }
2019-06-21T17:23:27.904Z    cc865442-8604-4f5c-8099-72eba87d9b2b    { ValidationException: The provided key element does not match the schema

不明显我的错误是什么？有想法吗？
