AWS Lambda - Create Thumbnail

Question

I am using AWS Lambda for creating resized thumbnails. The source is an S3 bucket and the destination is another S3 bucket. I was able to create the lambda function from Amazon CLI. The function is triggered whenever a new image is added to the source bucket. But, the resize/thumbnail creation is not working. I can see some issue in the CloudWatch Console.

The content of the uploaded ZIP package is:

CreateThumbnail.js, node_modules

Answer 1

Finally able to find the source of the bug. The command used to make the zip file was causing the issue.

The correct command is: zip -r CreateThumbnail.zip *
