Add a Create Note API

jayair · July 10, 2019, 9:32pm

Are you running this on Windows?

I get this error

$ serverless invoke local --function create --path mocks/create-event.json
Serverless: Bundling with Webpack...

I am getting the same result, the command line just return nothing. I have the version information like this. Besides, I cannot find the aws folder with config file and credential file in it. I do exactly the same as the tutorial.

This is my project directory along with my serverless.yml. I’ve changed the region to the right one with my dynamo so that shouldn’t be a problem.

LDY1998 · July 29, 2019, 2:34am

Never mind, I solve the problems. My mocks, libs and create.js are in wrong folder. However I do notice that in create.js, item’s fields are not exactly like the ones in tutorial. It should be ‘userid’ and ‘noteid’ instead of ‘userId’ and ‘noteId’

Otherwise you will get a validation exception!

jayair · August 4, 2019, 12:18am

Hmm that looks like an older version of the tutorial? Some of the babel presets in that error are pretty old.

jayair · August 4, 2019, 12:18am

Hmm those depend on what was set while creating the table. We use camel case throughout the tutorial.

I was wondering why do we use PUT in order to create entry in Dynamo. Why did not we use POST? Do they differ ?

As far as I know, generally, we use POST for creating new entries, and for the PUT to update the existing entries.

jayair · September 2, 2019, 3:42pm

If you are referring to HTTP POST vs PUT that doesn’t apply to DynamoDB. We use the put method in the DynamoDB Client SDK - https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB/DocumentClient.html#put-property.

Hi, using windows. No idea what i’ve done wrong, i’ve just copied and pasted for the most part, can you please assist:

Seems my node version was simply too old, updated and now fixed. Maybe a warning of the minimum node could be checked too?

jayair · September 28, 2019, 6:21pm

So it is working now after you updated your Node version?

leosole · October 21, 2019, 9:28pm

When a give the command
serverless invoke local --function create --path mocks/create-event.json
nothing happens

jayair · October 26, 2019, 2:29am

To debug this try:

$ SLS_DEBUG=true serverless invoke local --function create --path mocks/create-event.json

Mtd · October 29, 2019, 5:19pm

I followed the tutorial pretty easily until I got to getting a response

  message: 'One or more parameter values were invalid: Missing the key userid in the item',
  code: 'ValidationException',
  time: 2019-10-29T17:17:03.743Z,
  requestId: 'B53FTSNP519K6KN7NPLADF4SNRVV4KQNSO5AEMVJF66Q9ASUAAJG',

Copied the codes exactly, I’m in the us-east-1 region, all my AWS credentials are set up correctly.

Is the create-event.json wrong? Aren’t you supposed to specify userid when writing to the table? Am I literally supposed to use USER-SUB-1234 as the cognito ID or an actual ID from my Cognito pool?

jayair · November 3, 2019, 1:30am

Just a heads up we use userId instead of userid in the tutorial. So make sure you are using the right one.

Allirix · November 4, 2019, 7:45am

I have a problem with serverless invoke local --function create --path mocks/create-event.json as well.

I get the output:

Serverless: DOTENV: Could not find .env file.

Adrian · November 5, 2019, 4:48am

I was also getting

Serverless Error ---------------------------------------
Function "create" doesn't exist in this Service

Am running in Windows. I got past this error by removing the comments from functions part of the serverless.yml file.

functions:
  create:
    handler: create.main
    events:
      - http:
          path: notes
          method: post
          cors: true
          authorizer: aws_iam

Now onto troubleshooting the next issue! status code 500 (rofl)

jayair · November 16, 2019, 6:09pm

Yeah, usually these errors are caused by indenting issues in the serverless.yml.

mathewgries · December 11, 2019, 10:08pm

Make sure you are in the right directory when running the command. Happened to me, then realized I was running it from the libs directory. You have to run it from the root directory based on your --path parameter. I know this is a late reply, but in case this happens to any one else. It will run the command, and then just go to a new line in the command prompt/terminal with no error if you are not running the command at the right directory level.

Hi all what have I done wrong that I’m getting eslint strict errors? There’s a time and place for these nitpicks but not while I’m exploring and they’re holding me up. Any guidance as to what I did wrong / how to fix it would be most appreciated

I tried to soften the rules in an eslintConfig section inside package.json but it doesn’t seem to be respecting it:

  "eslintConfig": {
    "extends": "eslint-config-serverless",
    "rules": {
      "whatever": "blah",
      "semi": "warn",
      "space-before-function-paren": "warn",
      "no-trailing-spaces": "warn"
    }

boxabirds · December 13, 2019, 5:03am

As an interim to this I looked at the configuration for serverless-bundle and that helped – I disabled eslint for now by adding this into serverless.yml

custom:
  # for serverless-bundle -- webpack wrapper
  bundle:
    sourcemaps: true      # Enable source maps
    caching: false        # While in development don't cache
    stats: false          # Don't print out any Webpack output
    linting: false        # Disable linting as a part of the build process
