Dynamic ARN to Cognito authorizer

[RobertBrewitz]

I managed to get it working, building a Cognito User Pool Authorizer on the fly to put as the function authorizer arn.

Authorizer Config
Function config

It’s part of my Serverless Yeoman Generator.

Hope it helps!

Took a couple of days to figure it out, writing tests and debugging the resource builders of aws provider.

Have a look here, may help you, unless you provide a string to arn , the resource build in serverless assumes you’re trying to reference a lambda function to make the authorization, and can only build that kind of authorizer for you: https://github.com/serverless/serverless/blob/master/lib/plugins/aws/package/compile/events/apiGateway/lib/authorizers.js#L27
