AWS Serverless - adding response headers

Question

I'm following the documentation in order to set response headers. I'm doing so because CORS is not letting me do anything.

Anyways, the docs ( https://www.serverless.com/framework/docs/providers/aws/events/apigateway/#responses ) says I can do it like this:

events:
  - http:
      method: get
      path: whatever
      response:
        headers:
          Content-Type: "'text/html'"

However, it seems like the docs aren't up to date because serverless is complaining when deploying, Serverless: Configuration warning at 'functions.myFunction.events[1].httpApi': unrecognized property 'response'

How do you set response headers in the newest version?

Thanks!

Answer 1

That error appears to be coming from an httpApi event, not the http event you included in your question. Do you perhaps have another event with the type httpApi elsewhere in your serverless.yaml ? If so, it will break if you include a response in it because it uses a different schema than the regular http event type.
