Do I need to import AWS SDK into lambda - node.js

Question

Might be a dumb question, but couldn't find a clear answer on stack/aws docs. My assumption is that it should be built in to lambda.
I am running Node10.x, with Axios module, in AWS Lambda. I have a successful function which checks a DNS/EC2/Endpoint pathway and returns the proper response. I want to automate it so it checks, lets say...every 10 minutes. It will notify me in SES if there is an error, and do nothing if its a good response.
All the functionality works, except I am having trouble getting SES integrated. inside the if statement below, i have added this code, the console.log works, so its just the SES part im having issues with.
exports.handler = async (event, context) => {
let aws = require('aws-sdk');
let ses = new aws.SES({
region: 'us-east-1'
});
let data = "document_contents=<?xml version=\"1.0\" encoding=\"UTF-8\"?><auth><user>fake</user><pass>info</pass></auth>";
var axios = require("axios");
var config = {
headers: { 'Content-Type': 'text/xml' },
};
let res = await axios.post('https://awebsiteidontwanttogiveout.com', data, config);
let eParams;
if (res.status === 200) {
console.log("Success");
eParams = {
Destination: {
ToAddresses: ["banana#apples.com"]
},
Message: {
Body: {
Text: {
Data: "Test SUCCESSFUL"
}
},
Subject: {Test SUCCESSFUL"
}
},
Source: "banana#apples.com"
};
ses.sendEmail(eParams);
}
if (res.status != 200) {
console.log("Failure");
eParams = {
Destination: {
ToAddresses: ["banana#apples.com"]
},
Message: {
Body: {
Text: {
Data: "Test FAIL"
}
},
Subject: {
Data: "Test FAIL"
}
},
Source: "banana#apples.com"
};
ses.sendEmail(eParams);
}
};
I'm getting a time out after 3 seconds. I uploaded a zip file to node, with dependencies. do I need to install AWS SDK and upload that with the file? shouldn't it be built in somehow? am I missing something in my SES call?
thanks

There are two issues to address:
sendEmail is an async function from AWS SDK, you have to use:
await ses.sendEmail(eParams).promise()
or else, Lambda would end execution before sendEmail method completes.
Lambda's default timeout is 3 seconds. This can be increased to a max of 15 minutes in the Lambda configuration.
