Stuck on an issue?

I’m trying to trigger a lambda to update an Elastic Search instance whenever changes are made to DynamoDB. I have the stream set up in my serverless.yaml file, and when I deploy it, the lambda is triggered. However, when I run this with serverless-offline, the function is not triggered.

Here is my serverless.yaml

service: my-service

plugins:
  - serverless-dynamodb-local
  - serverless-offline

custom:
  tableName: "dynamodb-${self:provider.stage}"
  dynamodb:
    start:
      migrate: true

provider:
  name: aws
  runtime: nodejs6.10
  stage: dev
  region: ca-central-1
  iamRoleStatements:
    - Effect: Allow
      Action:
        - dynamodb:Query
        - dynamodb:Scan
        - dynamodb:GetItem
        - dynamodb:PutItem
        - dynamodb:UpdateItem
        - dynamodb:DeleteItem
        - dynamodb:DescribeStream
        - dynamodb:GetRecords
        - dynamodb:GetShardIterator
        - dynamodb:ListStreams
      Resource:
        - { "Fn::GetAtt": ["DynamoDbTable", "Arn" ] }

functions:
  # Request that should trigger function
  add:
    handler: handler.add
    events:
      - http:
          path: api/add
          method: POST
  # Function that should be triggered
  updateIndices:
    handler: handler.updateIndices
    events:
      - stream:
          type: dynamodb
          arn:
            Fn::GetAtt:
              - DynamoDbTable
              - StreamArn
          startingPosition: LATEST
          batchSize: 1
          enabled: true

resources:
  Resources:
    DynamoDbTable:
      Type: "AWS::DynamoDB::Table"
      DeletionPolicy: Delete
      Properties:
        TableName: ${self:custom.tableName}
        AttributeDefinitions:
          - AttributeName: id
            AttributeType: S
        KeySchema:

            KeyType: HASH

        StreamSpecification:
          StreamViewType: NEW_AND_OLD_IMAGES
    ElasticSearchInstance:
      Type: "AWS::Elasticsearch::Domain"
      Properties:
        EBSOptions:
          EBSEnabled: true
          VolumeType: gp2
          VolumeSize: 10
        ElasticsearchClusterConfig:
          InstanceType: t2.small.elasticsearch
          InstanceCount: 1
          DedicatedMasterEnabled: false
          ZoneAwarenessEnabled: false
        ElasticsearchVersion: "6.0"

Is what I’m trying to do possible with serverless-dynamodb-local? Or is there more configuration that needs to be added to fire this function locally?

Thanks for the help!
