Using CORS with AWS SAM

Question

I've created a few Lambda functions that get triggered by API-Gateway events.

Now I want to enable CORS for these endpoints, but it doesn't seem to work. In the last few versions of AWS SAM the CORS functionality was added or updated, but I still can't get it to work.

This is what I tried:

Gobals:
  Api:
    Cors: "'*'"

Answer 1

You forgot to add the AllowOrigin property.

It needs to look like this:

Globals:
  Api:
    Cors:
      AllowOrigin: "'*'"
