Request should be successful with request successfully getting routed with Route53 -> CloudFront -> API Gateway -> AppSync -> Lambda. Correct GraphQL API response should be returned as follows:

}
Also note that above response is also returned when we call the API with CloudFront URL directly (for e.g. https://cbc39fc5.cloudfront.localhost.localstack.cloud/api)
So it looks like there is some issue with CloudFront not correctly passing the URL to call API gateway. The error says:
requests.exceptions.InvalidURL: Invalid URL \'https:///default/api\': No host supplied"}
The URL should have been https://8w2qtglsa9.execute-api.us-east-1.amazonaws.com/default/api. For some reason CloudFront is not adding Domain Name specified in the distribution config.
I have verified that localstack works with Route53 -> CloudFront -> S3 integration. You can also test this by following these steps:
- Run following commands:
cd route-53-test tflocal init tflocal apply -lock=false -auto-approve awslocal s3 cp /tmp/hello.txt s3://mybucket/hello.txt --acl public-read - Use following CURL command to get S3 object:
curl -k https://localstack-posaas.mypostureservice.name/mybucket-ahsanb/hello.txt
