Troubleshooting AWS unauthorized errors in lambda requests

This is mainly for node.js but might apply to other environments. Unsure.

If you are running a AWS Lambda function that calls another AWS service and getting an error about invalid tokens or other access denied errors, do this:

Check IAM

The role assigned to your lambda function will need permission to perform the actions. Check IAM and make sure the role has all the permissions.

HLS streaming from node

Provided that you already have a file or stream segmenter generating your .m3u8 playlist and .ts segment files (such as the ffmpeg 'hls' muxer), this little node server will serve up those files to an HLS compatible client (e.g. Safari). If you're using node for your streaming app already, this obviates the need to serve the HLS stream from a separate web server.
