Bug reproducer

This project is to demonstrate the bug middyjs/middy#1263

To reproduce

Manually

1. Login to aws account
2. npm run cdk deploy
3. Invoke the lambda using the test console with payloadInputa.json
4. Lambda responds with

{
  "statusCode": 200,
  "body": "{\"hi\":\"there\"}",
  "headers": {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "http://localhost:3000",
    "Vary": "Origin"
  }
}

4. Invoke the lambda using the test console with payloadInputb.json, Access-Control-Allow-Origin is still http://localhost:3000 instead of expected https://example.org.

{
  "statusCode": 200,
  "body": "{\"hi\":\"there\"}",
  "headers": {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "http://localhost:3000",
    "Vary": "Origin, Origin"
  }
}

Automatically

1. Login to aws account
2. npm run cdk:integ
