Global Secondary Index is not working

[yukitaka13-1110]

I defined dynamodb table with global secondary index.
I requested query with GSI.
But an error occurred.
Is This plugin not support GSI?

request.vtl

{
    "version" : "2017-02-28",
    "operation" : "Query",
    "index" : "groupId-index",
    "query" : {
        "expression": "groupId = :groupId",
        "expressionValues" : {
            ":groupId" : $util.dynamodb.toDynamoDBJson($ctx.args.groupId)
        }
    }
}

serverless.yml

Hello, maybe is an issue with your code. I can use global and local secondary index just fine.
Check the indentation on your YAML, try to create a smaller yaml with just an index.

this is my YAML that works:

Resources:
  kraken:
    Type: AWS::DynamoDB::Table
    Properties:
      TableName: ${self:custom.krakenTableName}
      AttributeDefinitions:
        - AttributeName: PK
          AttributeType: S
        - AttributeName: SK
          AttributeType: S
        - AttributeName: guidChannelRaw
          AttributeType: S
      KeySchema:
        - AttributeName: PK
          KeyType: HASH
        - AttributeName: SK
          KeyType: RANGE
      BillingMode: PAY_PER_REQUEST
      GlobalSecondaryIndexes:
      - IndexName: chRawRef-index
        KeySchema:
        - AttributeName: guidChannelRaw
          KeyType: HASH
        Projection: 
          ProjectionType: ALL

For me the index is working and present but always empty, result that the query returns nothing.
I tried to see if it was not a spelling mistake in any of the attribute but nothing.

Any idea? I'm blocked in my local testing since I cannot replicate the remote behavior.

My bad if you range key is empty it won't be indexed, in my sample the mistake is I wanted to index organisationID, updatedAt not createdAt
