AWS SDK for JavaScript in the browser and Node.js (In Maintenance Mode, End-of-Life on 09/08/2025). The AWS SDK for JavaScript v3 in the browser and Node.js is available here: https://github.com/aws/aws-sdk-js-v3
I'm runing Node 20.14.0 and aws-sdk/client-s3 ^3.609.0
The error occurs just when I import the library:
const { PutObjectCommand, S3Client } = require("@aws-sdk/client-s3");
/node_modules/@aws-sdk/client-s3/dist-cjs/index.js:282 useFipsEndpoint: options.useFipsEndpoint ?? false
Invalid or unexpected token (it points to ??)
To double check I'm using the correct runtime I added this line to my script:
console.log(Node.js version: ${process.version});
Expected Behavior
It shouldn't have thrown an error.
Current Behavior
node_modules/@aws-sdk/client-s3/dist-cjs/index.js:282 useFipsEndpoint: options.useFipsEndpoint ?? false, SyntaxError: Invalid or unexpected token at Module._extensions..js (node:internal/modules/cjs/loader:1416:10)
This issue happened because I was calling the script with esm flag, like
"node -r esm download.js"
I don't know If this should work either way, but I managed to make it work so I'm closing the tickets.
