Event Data Keys Inconsistency

[tadi-maz]

Hi I've noticed that an event in EventBridge is passed in this format (as seen from cloudwatch logs):

{
    source: "some source",
    "detail-type": "some detail-type",
    detail: { someCustomDetail : "detail"}
}

whereas the plugin passes data in this format

      {
        Source: "some source",
        DetailType: "some detail-type",
        Detail:  { someCustomDetail : "detail"}
      }

Is there a way to ensure these are consistent?

Hi, can you show me your code. The consuming functions do receive the correct format:

{
  version: '0',
  id: 'xxxxxxxx-xxxx-xxxx-xxxx-1605085184180',
  source: 'acme.newsletter.campaign',
  account: '',
  time: '2020-11-11T08:59:44.180Z',
  region: 'eu-west-1',
  resources: [],
  detail: { 'E-Mail': 'some@someemail.some' },
  'detail-type': 'UserSignUp'
}

Using the following example code:

serverless.yml:

plugins:
  - serverless-webpack
  - serverless-offline
  - serverless-offline-aws-eventbridge
  
custom:
  webpack:
    webpackConfig: ./webpack.config.js
    includeModules: true
  serverless-offline:
    host: 0.0.0.0
  serverless-offline-aws-eventbridge:
    port: 4010
    debug: true

provider:
  name: aws
  runtime: nodejs12.x
  stage: dev
  region: eu-west-1
 
functions:
  publishEvent:
    handler: events.publish
    events:
      - http:
          path: publish
          method: get

  consumeEvent:
    handler: events.consume
    events:
      - eventBridge:
          eventBus: marketing
          pattern:
            source:
              - acme.newsletter.campaign

events.js

import AWS from 'aws-sdk';

AWS.config.update({
  apiVersion: '2015-10-07',
  accessKeyId: "YOURKEY",
  secretAccessKey: "YOURSECRET",
  region: "eu-west-1"
});

export const publish = async () => {
  try {
    const eventBridge = new AWS.EventBridge({
      endpoint: 'http://127.0.0.1:4010',
      region: 'eu-west-1'
    });

    const test = await eventBridge.putEvents({
      Entries: [
        {
          EventBusName: 'marketing',
          Source: 'acme.newsletter.campaign',
          DetailType: 'UserSignUp',
          Detail: `{ "E-Mail": "some@someemail.some" }`,
        },
      ]
    }).promise();
  } catch (e) {
    console.error(e);
    return { statusCode: 400, body: 'could not publish' };
  }
  return { statusCode: 200, body: 'published' };
}

export const consume = async (event, context) => {
  console.log(event);
  return { statusCode: 200, body: 'consume' };
}

Using babel and webpack to transpile everything..
