Configure Route 53 domain to new version Amplify app

Question

I have a domain registered in Route 53 and an app hosted in old Amplify. I configure the alias of domain's A record type to the cloudfront of the Amplify app which worked.

Now since I need advanced features such as SSR, I built a new Amplify version app (which shows preview). But I can't find the cloudfront of the new app so that I can't change the A record type to new cloudfront. Then I tried to add CNAME record type which doesn't allow me and the error message is (InvalidChangeBatch 400: RRSet of type CNAME with DNS name  is not permitted at apex in zone).

So, my question is how can I change the domain redirect to my new app.

Answer

The zone apex record cannot be a CNAME, so in these circumstances use an ALIAS record to point to an AWS resource https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resource-record-sets-choosing-alias-non-alias.html

> Unlike a CNAME record, you can create an alias record at the top node of a DNS namespace, also known as the *zone apex*. For example, if you register the DNS name example.com, the zone apex is example.com. You can't create a CNAME record for example.com, but you can create an alias record for example.com that routes traffic to www.example.com (as long as the record type for www.example.com is not of type CNAME).
