I need to be able to catch the error that occurs during the process of sending an email using Express and AWS SES. If there occurs an error, wrong email for example, the API itself shows a CORS error while in nodemon console the error is logged there.

const AWS = require('aws-sdk');

const SES_CONFIG = {
    accessKeyId: '...',
    secretAccessKey: '...',
    region: '...',
};

const AWS_SES = new AWS.SES(SES_CONFIG);

let sendEmail = (recipientEmail, name) => {
    let params = {
        Source: '...@gmail.com',
        Destination: {
            ToAddresses: [
                recipientEmail
            ],
        },
        ReplyToAddresses: [],
        Message: {
            Body: {
                Html: {
                    Charset: 'UTF-8',
                    Data: 'This is the body of my email!',
                },
            },
            Subject: {
                Charset: 'UTF-8',
                Data: `Hello, ${name}!`,
            }
        },
    };
    return AWS_SES.sendEmail(params).promise();
};

The API endpoint:

router.post('/emailTest', async (req, res) => {
    try {
        sendEmail('...@gmail.com', '...', function (err, data) {
            if (err)
                res.send(err);
            res.send(data);
        });

    } catch (error) {
        res.json({
            Status: 500,
            header: 'Error',
            message: 'Internal Server Error. ' + error.message
        });
    } })
