Trying to follow a guide about serverless, getting an error

Serverless Framework
1

Hi
First, I im a newbi to the aws stack and serverless, so if my question is nobbish, im sorry in advance… :slight_smile:

Im following the guide from:
https://medium.freecodecamp.com/building-a-nodejs-microservice-on-aws-lambda-6adb6da53cbb#.1gwx3zrmz

I have cloned the repo from git, deployed, and every thing seams fine until i run a test, so the code should be ok.

Do my lampda or the apiGateway lack Read/Write Access rights to Dynamodb? im a bit lost here, Any advices ?

When i test an post/insert im getting the error
{
“errorMessage”: “Error creating pet”
}

and the log:

Yeah, it could definitely be a permissions issue. I looked through the blog post and code, and couldn’t find where he was setting that up. Usually you would do it in serverless.yml but there’s nothing there. Also, did you (manually via the console) create the “Pets” table in DynamoDb?

I created the pets table manually. Ill have a look at the serveress.yml, that give me some kind of direction for finding the problem, Thanks for answering my question :slight_smile:
