I think the execution role that you have assinged to lambda doesn't have permission on the buckets you are using. You can try this like go to s3 bucket you are using and click the properties tab on right side and than go in permissions section.You can give appropriate access in that or for testing purpose you case give access to everyone. http://docs.aws.amazon.com/AmazonS3/latest/dev/intro-managing-access-s3-resources.html

Thanks. I fixed it by modifying the bucket names, with my actual bucket names. Nowhere in the tutorial does it say that the bucket names have to be changed
