Can I use an IndexName for a DynamoDB proxy?

[ffiorillosparkdigital]

Hi! I'm looking for a way to set up an endpoint that would use an index based on GSI, instead of using the primary Hash/Sort Key. Is this possible? I don't see any examples in the docs.

I tried adding this, but causes an error:
IndexName: user_id_index

apiGatewayServiceProxies:
- dynamodb:
path: /myapp/by_user/{user_id}
method: get
tableName: { Ref: 'myTable' }
IndexName: user_id_index
hashKey:
pathParam: user_id
attributeType: S
action: GetItem
cors: true

results in:

child "dynamodb" fails because ["IndexName" is not allowed]

Any help is appreciated. Thanks!

Right now, this plugin does not support for index of DynamoDB. But always welcome to proposal or pull request by anyone 👍

@horike37 thank you for your response.
After doing some more research, it looks like this could be achieved by using a custom Mapping Template in the API Gateway endpoint . Can this be achieved somehow in Serverless with the plugin?

Thanks!
