使用node.js从lamda查询aurora serverless db时出错-MissingRequiredParameter:缺少必需的密钥'；秘书长'；在params中

我使用下面的代码通过node.js中编写的lambda funntion查询aurora serverless db中的表。我已经用lambda_层结构正确地打包了我的代码，并在aws lambda中上传了zip，并且已经应用了所有必需的策略，但仍然出现错误：

 const AWS = require('aws-sdk')
    const RDS = new AWS.RDSDataService()
    
    exports.handler = async (event, context, callback) => {
    
      try {
    
        const params = {
          awsSecretStoreArn: 'xxxxxx',
          dbClusterOrInstanceArn: 'xxxxx',
          sql: `SELECT * FROM employee WHERE id = :id`,
          parameters: [
            {
              name: 'id',
              value: {
                "longValue": 1
              }
            }
          ],
          database: 'test_data_api'
        }
    
        let data = await RDS.executeStatement(params).promise()
    
        console.log(JSON.stringify(data, null, 2))
     
        return 'done'
    
      } catch(e) {
        console.log(e)
      }
    }

但不幸的是，出现了以下错误：
