使用node.js从lamda查询aurora无服务器数据库时出错-MissingRequiredParameter：在参数中缺少必需的键'secretArn'

问题描述

我正在使用以下代码通过在node.js中编写的lambda函数查询aurora无服务器db中的表。我已经使用lambda_layer结构正确打包了我的代码，并在aws lambda中上传了zip文件，并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)
      }
    }

但不幸的是出现以下错误：
