The runtime line in the serverless.yml file should read:

runtime: nodejs6.10

Looks like you updated it for the prior page for Serverless 1.10ā€™s support of AWS/Node6 but missed this one. Minor thing but thought youā€™d want to know.

Oh yeah youā€™re right. Just fixed it - 87587868b0829ded83cfde2a00e7a5af8f441518

When testing the code, Iā€™m getting a 500 response. How do I troubleshoot this?
The only thing Iā€™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.

@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

That should give you a clue.

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

Hello,
When I run the command : serverless webpack invoke --function create --path event.json
I have this :

{ statusCode: 500,
  headers: 
   { 'Access-Control-Allow-Origin': '*',
     'Access-Control-Allow-Credentials': true },
  body: '{"status":false}' }

content of DynamoDB object :

      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,

        convertResponseTypes: true,
        correctClockSkew: false,
        customUserAgent: null,
        dynamoDbCrc32: true,
        systemClockOffset: 0,
        signatureVersion: 'v4',
        signatureCache: true,
        retryDelayOptions: {},

     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 :

        retryable: true } } }

I Follow the tutorial (2 times :slight_smile: ), but impossible to understand what is my problem.
I used the region eu-west-2 instead of us-east-1.

Did I forget something ?

@flocve Could you double check if these two files exist ~/.aws/config and ~/.aws/credentials

~/.aws/config should look like

[default]
region = eu-west-2

~/.aws/credentials should look like

[default]
aws_access_key_id = AKIXXXXGMPQAP123XXXX
aws_secret_access_key = JOsGrXxxXl8o8bXxXxbOf1RoDw2guXXxxXXxx123

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.

@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 Iā€™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?

Iā€™m getting the error above when trying to run the test, not sure where to proceed from here.

Update: OK, my bad, turns out ā€˜functionsā€™ isnā€™t aligned correctly and was tabbed, making it a property of provider. Untabbed it and works perfectly!

@ryanjcruz Glad you figured it out. Just noticed somebody else is having a similar issue as well.

When I invoke the create function I got the above error, I did everything as mentioned in the tutorial, I couldn't able to trace the error, kindly help me to resolve the issue.
If I change the callback function to ES6  promise then I got the 500 error response before that I got 200 response...

UPDATE: I wrongly passed the arguments name in the dynamodb-lib.js, it works fine now.

When running serverless webpack invoke --function create --path event.json, I get the following:

Unexpected token import

From @go4cas on Sun May 21 2017 09:05:02 GMT+0000 (UTC)

Okay, I fixed this with:

npm install --save-dev babel-preset-es2015

And then, changed .babelrc file:

{
  "plugins": ["transform-runtime"],
  "presets": ["react-app","es2015"]
}
