Description

When Cors is enabled for multiple endpoints that have the same path the Methods are merged into the one CORS OPTION response, but header or origin config created by the separate http events isn't merged into one OPTION request. Following is an example:

functions:
  blog:
    handler: handler.handler
    events:
      - http:
          path: posts
          method: get
          cors:
            origins:
               - http://example.com
      - http:
          path: posts
          method: post
          cors: 
            origins:
               - http://example2.com
      - http:
          path: posts/{id}
          method: put
          cors:
            headers:
               - TestHeader
      - http:
          path: posts/{id}
          method: delete
          cors:
            headers:
               - TestHeader2

The resulting OPTION CORS request should return both origins and both headers as allowed headers and origins, but it doesn't. This was brought up for methods in #1960 and fixed in #1951 for methods, but not fixed for others.

Similar or dependent issues:

• CORS not working for multiple methods on same endpoint #1960
• New CF Logical IDs #1951
