3.1.3 assumes you have created a package.json "during installation", but there is no npm init installation step in the book.

Also, there is no corresponding step to create an Elastic Transcoder pipeline to "Don’t forget to set PipelineId to the corresponding Elastic Transcoder pipeline you created earlier."

Am I missing a chapter?

Another errata:

npm install run-local-lambda –-save-dev

should be

npm install –-save-dev run-local-lambda

Ok, I found all of this in Appendix B. Maybe I missed a clear reference to follow those instructions.
