Error: Cannot read property 'Topic' of undefined

I touch a single file in S3 bucket

s3touch s3://bucket/folder/file.jpg

and get this error:

/usr/local/lib/node_modules/s3touch/node_modules/aws-sdk/lib/request.js:30
            throw err;
            ^

Thanks in advance.

It looks like line 35 in index.js explicitly references a TopicConfiguration key for SNS topic notifications. However, when I tried to touch a file in a bucket that had a lambda function listening to the ObjectCreated event I got the same error as you.

Same - trying to trigger a Lambda event from file activity

@RichardCullen I "solved" it by changing the Lambda to listen for an SNS topic message instead of a Lambda event. It's a little harder to parse, but it works for my needs.
