_From @jayair on Mon Apr 10 2017 00:59:33 GMT+0000 (UTC)_ Link to chapter - [http://serverless-stack.com/chapters/add-a-create-note-api.html](http://serverless-stack.com/chapters/add-a-create-note-api.html) _Copied from original issue: [https://github.com/AnomalyInnovations/serverless-stack-com/issues/23](https://github.com/AnomalyInnovations/serverless-stack-com/issues/23)_ ---

_From @nerdguru on Mon Apr 10 2017 15:01:59 GMT+0000 (UTC)_ The runtime line in the serverless.yml file should read: runtime: nodejs6.10 Looks like you updated it for the prior page for Serverless 1.10’s support of AWS/Node6 but missed this one. Minor thing but thought you’d want to know. ---

_From @jayair on Mon Apr 10 2017 17:03:25 GMT+0000 (UTC)_ Oh yeah you’re right. Just fixed it - 87587868b0829ded83cfde2a00e7a5af8f441518 ---

_From @geirman on Fri Apr 14 2017 23:48:42 GMT+0000 (UTC)_ When testing the code, I’m getting a 500 response. How do I troubleshoot this? The only thing I’ve done differently is change all instances of `us-east-1` to `us-east-2` to match values I see in my pool id, pool arn, identity pool id, etc. Seemed like the right thing to do. ---

_From @jayair on Sat Apr 15 2017 00:00:02 GMT+0000 (UTC)_ @geirman that would be a DynamoDB related error. Can you try printing out the error object in this line - [https://github.com/AnomalyInnovations/serverless-stack-com/blame/master/\_chapters/add-a-create-note-api.md#L56](https://github.com/AnomalyInnovations/serverless-stack-com/blame/master/_chapters/add-a-create-note-api.md#L56) That should give you a clue. ---

_From @geirman on Sat Apr 15 2017 05:17:05 GMT+0000 (UTC)_ Thanks, that helped. My problem was naming one of the keys `notesId` instead of `noteId` > ValidationException: One or more parameter values were invalid: Missing the key notesId in the item ---

_From @flocve on Mon Apr 17 2017 10:09:21 GMT+0000 (UTC)_ Hello, When I run the command : `serverless webpack invoke --function create --path event.json` I have this : ```auto { statusCode: 500, headers: { 'Access-Control-Allow-Origin': '*', 'Access-Control-Allow-Credentials': true }, body: '{"status":false}' } ``` content of DynamoDB object : ```auto Config { credentials: null, credentialProvider: [Object], region: 'eu-west-2', logger: null, apiVersions: {}, apiVersion: null, endpoint: 'dynamodb.eu-west-2.amazonaws.com', httpOptions: [Object], maxRetries: undefined, maxRedirects: 10, paramValidation: true, sslEnabled: true, s3ForcePathStyle: false, s3BucketEndpoint: false, s3DisableBodySigning: true, computeChecksums: true, convertResponseTypes: true, correctClockSkew: false, customUserAgent: null, dynamoDbCrc32: true, systemClockOffset: 0, signatureVersion: 'v4', signatureCache: true, retryDelayOptions: {}, useAccelerateEndpoint: false }, isGlobalEndpoint: false, endpoint: Endpoint { protocol: 'https:', host: 'dynamodb.eu-west-2.amazonaws.com', port: 443, hostname: 'dynamodb.eu-west-2.amazonaws.com', pathname: '/', path: '/', href: 'https://dynamodb.eu-west-2.amazonaws.com/' }, _clientId: 1 }, attrValue: 'S8' } ``` And the error is : ```auto CredentialsError: Missing credentials in config at ClientRequest.

I used the region **eu-west-2** instead of **us-east-1**. Did I forget something ? ---

_From @fwang on Tue Apr 18 2017 17:35:39 GMT+0000 (UTC)_ @flocve Could you double check if these two files exist ~/.aws/config and ~/.aws/credentials ~/.aws/config should look like ```auto [default] region = eu-west-2 ``` ~/.aws/credentials should look like ```auto [default] aws_access_key_id = AKIXXXXGMPQAP123XXXX aws_secret_access_key = JOsGrXxxXl8o8bXxXxbOf1RoDw2guXXxxXXxx123 ``` ---

_From @eliocapelati on Sat Apr 22 2017 23:11:35 GMT+0000 (UTC)_ Hello, Following these steps, I have been getting an error on LAMBDA\_PROXY function of api gateway. the response on request also includes the: ``` statusCode: 200, headers: { 'Access-Control-Allow-Origin': '*', 'Access-Control-Allow-Credentials': true, }, body: .... ``` and if a error (500) occur, the status code is 200. ---

_From @jayair on Sat Apr 22 2017 23:17:38 GMT+0000 (UTC)_ @eliocapelati can you show me the full response that you are seeing? ---

_From @jayair on Mon Apr 24 2017 20:15:31 GMT+0000 (UTC)_ @eliocapelati I’m a bit confused here. According to your code you are throwing the 404 error. That is how it should work right? There is no problem then right? ---
