I'm using Node 12.x version to write my Lambda function. Here is the Parsing error that I am getting. What could be the reason?
Update
const im = require("imagemagick");
const fs = require("fs");
const os = require("os");
const uuidv4 = require("uuid/v4");
const {promisify} = require("util");
const AWS = require('aws-sdk');
const resizeAsync = promisify(im.resize)
const readFileAsync = promisify(fs.readFile)
const unlinkAsync = promisify(fs.unlink)
AWS.config.update({region: 'ap-south-1'})
const s3 = new AWS.S3();
exports.handler = async (event) => {
let filesProcessed = event.Records.map((record) => {
let bucket = record.s3.bucket.name;
let filename = record.s3.object.key;
//Fetch filename from S3
var params = {
Bucket: bucket,
Key: filename
};
//let inputData = await s3.getObject(params).promise()
let inputData = await s3.getObject(params).promise();
//Resize the file
let tempFile = os.tmpdir() + '/' + uuidv4() + '.jpg';
let resizeArgs = {
srcData: inputData.Body,
dstPath: tempFile,
width: 150
};
await resizeAsync(resizeArgs)
//Read the resized File
let resizedData = await readFileAsync(tempFile)
//Upload the resized file to S3
let targetFilename = filename.substring(0, filename.lastIndexOf('.') + '-small.jpg')
var params = {
Bucket: bucket + '-dest',
Key: targetFilename,
Body: new Buffer(resizedData),
ContentType: 'image/jpeg'
}
await s3.putObject(params).promise();
return await unlinkAsync(tempFile)
})
await Promise.all(filesProcessed)
return "done"
}
Here is the same code. I am getting Unexpected token S3 error when hovering the red mark (shown in the image)
What you can do is, declare inputData as below and initialize it with the response from the getObject.
let inputData;
var params = {
Bucket: "examplebucket",
Key: "HappyFace.jpg"
};
s3.getObject(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else inputData = data; // successful response
});
