Description of changes:
Hi😀 Thanks for the useful patterns!

To prevent future deployment issues, I updated the Lambda Node.js runtime version to nodejs22.x.

While testing terraform-s3-object-lambda, I noticed that the Lambda runtime version nodejs16.x was deprecated. Although it's still deployable at the moment, it will not be allowed after October 1, 2025.

Check

terraform apply completed successfully and works good.

$ aws s3 cp ./images/sample.jpg s3://decent-raccoon-bucket --region eu-west-1
upload: images/sample.jpg to s3://decent-raccoon-bucket/sample.jpg

$ mkdir ./thumbs

$ aws s3api get-object --bucket resize-olap-i4x6dzs1zybd5unxx14qx7freuw1a--ol-s3 --key sample.jpg ./thumbs/sample-thumbnail.jpg --region eu-west-1

}

Thank you😀

note: Some error occurs. Because in Node.js 18 and later runtimes, AWS SDK v3 is bundled, so I rewrote it to v3. See articles below.

note: I added mkdir command because it had the following error.

$ aws s3api get-object --bucket decent-raccoon-bucket --key sample.jpg ./thumbs/sample-thumbnail.jpg --region eu-west-1
[Errno 2] No such file or directory: './thumbs/sample-thumbnail.jpg'
