Gitlab CI auto send email with information from Git release tag

I) Send email with AWS Lambda & AWS SES

1) Go to AWS SES and verify email identities ( source sender email)

2) Create AWS Lambda function

const aws = require("aws-sdk")

function generateEmailParams(subject, message) {
  const bodyHtml = `<html>
    <head></head>
      <body>
          <h1>Message from {SENDER_NAME}</h1>
          <h3>From: Sender</h3>
          <br/>
          <p>${message}</p>
      </body>
    </html>`

  return {
    Destination: {
      ToAddresses: [
        "[email protected]"
      ],
    },
    ReplyToAddresses: ["[email protected]"],
    Source: "[email protected]",
    Message: {
      Body: {
        Html: {
          Charset: "UTF-8",
          Data: bodyHtml,
        },
        Text: {
          Charset: "UTF-8",
          Data: message,
        },
      },
      Subject: {
        Charset: "UTF-8",
        Data: subject,
      },
    },
  }
}

function errorResponse(errors) {
  return {
    statusCode: 400,
    body: {
      success: false,
      errors,
    },
  }
}

function successResponse(message) {
  return {
    statusCode: 200,
    body: {
      success: true,
      message,
    },
  }
}

exports.handler = async event => {
  try {
    const { subject, message } = JSON.parse(event.body)
    const params = generateEmailParams(subject, message)
    const data = await new aws.SES()
      .sendEmail(params)
      .promise()
      .then(() => {
        return successResponse("Email sent")
      })
      .catch(error => {
        return errorResponse([error.message])
      })

    return data
  } catch (e) {
    return errorResponse([e.message])
  }
}

3) Generate Lambda function URL to use to invoke from CI

4) Navigate to IAM role and edit permission for sending email permission

5) Go to postman and test lambda function before

6) Create gitlab-ci.yml

#======INIT=========
stages:
  - test

#======JOBS=========

email_notify_prod_deployment:
  stage: test
  tags:
    - linux
    - autopilot-builder
  before_script:
    - apk update && apk add --no-cache git && apk add --no-cache curl
    - echo "Execute email_notify_prod_deployment section starts."
  script:
    - git fetch --tags
    - LATEST_TAG=$(git describe --tags $(git rev-list --tags --max-count=1))
    - echo $LATEST_TAG
    - TAG_AUTHOR=$(git show $LATEST_TAG --format='%an <%ae>' --no-patch | awk '{printf "%s<br>", $0}' | sed 's/"/\\"/g')
    - echo $TAG_AUTHOR
    - |
      curl --request POST \
      -H "Content-Type:application/json" \
      -d "{ \"subject\":\"$LATEST_TAG\", \"message\":\"$TAG_AUTHOR\" }" \
      "$SEND_EMAIL_LAMBDA_FUNCTION"

  after_script:
    - echo "Execute email_notify_prod_deployment section completes."
  only:
    - /^main$/
