I'm doing a tutorial(https://serverless-stack.com/) and when I get to the part where I interact with the backend with my react I get a CORS error saying that it can not communicate with my backend. Does someone have an idea how I would fix this? I read about adding the 'Access-Control-Allow-Origin' header but I am confused to where I should put it ?

Hi there, I'm one of the authors of the Serverless Stack guide. You can compare the serverless.yml settings to the one from the guide https://github.com/AnomalyInnovations/serverless-stack-demo-api/blob/master/services/notes/serverless.yml and also make sure the headers are being set correctly https://github.com/AnomalyInnovations/serverless-stack-demo-api/blob/master/services/notes/libs/handler-lib.js#L27.
