AWS Lambda Postgres数据库连接在时间间隔上的问题

Please see below the error that I am getting while executing a lambda after 
a particular time interval. Any suggestions will be appreciated.

  

“ pid”：1，       “级别”：50，       “呃”： {           “ message”：“连接意外终止”，           “ name”：“ SequelizeConnectionError”，           “ stack”：“ SequelizeConnectionError：连接意外终止\ n

The DB connection code is as below

const sequelize = new Sequelize(process.env.DB_NAME, process.env.DB_USER, 
process.env.DB_PWD, {
host: process.env.DB_HOST,
dialect: 'postgres',
logging: process.env.DB_SHOW_LOGS === 'true',
port: process.env.DB_PORT,
pool: {
 max: 5,
 min: 1,
 acquire: 30000,
idle: 10000
},
operatorsAliases: false
});
