AWS Lambda fails when I import an image. Runtime.UserCodeSyntaxError

Context

I am working on a Lambda function in my index.js file to help me add watermark on images using Sharp.

This is the error I am getting.

2022-04-01T20:33:49.269Z    undefined   ERROR   Uncaught Exception  {"errorType":"Runtime.UserCodeSyntaxError","errorMessage":"SyntaxError: Invalid or unexpected token","stack":["Runtime.UserCodeSyntaxError: SyntaxError: Invalid or unexpected token","

The Culprit

I realized the issue was happening when I imported a .png file.

const sharp = require('sharp');
const { S3 } = require('aws-sdk');
const stream = require('stream');
const playButtonPng = require('./assets/playButton.png'); // When this is commented out, the Lambda works

I thought about maybe "pulling" this image from S3, but it becomes complex since Sharp requires a "real image."

So my question is: is it possible to import a local .png in a lambda function? I tried investigating but did not find any results.

Other Things I've tried:

load PNG file by readFile / readFileSync available in fs module.

var fs = require('fs')
const playButtonPng = fs.readFileSync('./assets/playButton.png')
