Error at Protocol._enqueue (/var/task/node_modules/mysql/lib/protocol - mysql

Question

Currently I want to access MySQL Aurora DB from inside a lambda function.
I have both the Aurora and the lambda in same VPC, subnets and security group.
The following is the lambda function code:
console.log("Welcome to lambda")
var connection = mysql.createConnection({
host: 'aurora-test1-us-mysql-multilevel.cluster-cutke7yxox3c.us-west-2.rds.amazonaws.com',
database: 'aurora-test1-us-mysql-multilevel',
user: "***",
password: "***",
});
console.log("createConnection",connection)
let con = connection.connect();
console.log("connect:",con)
const query = connection.query('USE feature;SELECT * FROM feature;')
console.log("query",query)
connection.end();
return {
statusCode: 200,
body: "HELLO KIMOO!!! Welcome TO AURORA DB" + "Database Created2"
}
}
catch(err)
{
console.log("Error caught",err)
return {
statusCode: 500,
body: JSON.stringify({
message: 'Error: ' + err
})
}
}
The following is the output received from logging the query
_events: [Object: null prototype] {
error: [Function (anonymous)],
packet: [Function (anonymous)],
timeout: [Function (anonymous)],
end: [Function (anonymous)]
},
_eventsCount: 4,
_maxListeners: undefined,
_callback: undefined,
_callSite: Error

I don't understand what does this error mean and how can I connect to Aurora and retrieve data from it successfully
Note:
I'm using Typescript
I'm using mysql library
