Issues with Amazon IoT Rules with DynamoDB and Lambda

Question

I am currently going through the "Quick Start" tutorial for Amazon IoT and I have gotten to the point where I am configuring my rules and test rules. I can see my rules in my aws console under Amazon IoT, along with my thing, cert, and policy. I am using Mosquitto like they suggest for testing it, and I can see my message when I subscribe to my topic.

But I am having an issue that, when I publish a message, I don't see anything in my DynamoDB or the CloudWatch logs from Lambda. And in IoT, I am able to create a resource and see my roles, db table, and lambda function as if it's working. I am keeping to what the tutorial is saying and nothing extra. I can't find any other forum that has discussed Amazon IoT or is having this issue.

Answer 1

Found the solution, it was an error in the AWS Quickstart tutorial.

Look at this thread: https://forums.aws.amazon.com/thread.jspa?threadID=217825&tstart=0

• The range timestamp field must be of type String and not Number
• The hashKeyValue in the json must be "${topic()}" instead of "${topic(3)}"
