hostedZoneNameServers can be undefined in PublicHostedZone

Reproduction Steps

Using Route53 > PublicHostedZone.hostedZoneNameServers.

Unfortunatly, I can’t export these NS as a CfnOutput because hostedZoneNameServers can be undifiened (why ? I’m using PublicHostedZone) : Type 'undefined' is not assignable to type 'string'

And I have to set NS as records in another account (who drive the Main Public HostedZone).

So, is it a bug for the PublicHostedZone ? And of course, can’t write the output in a file (with CDK –outputs-file) to use it in my other Account.

So, what can I do ?

Thanks in advance.

@Cloudrage PublicHostedZone implements IHostedZone which represents the properties for all hosted zones. The reason the property may be undefined is because any hosted zone should be usable in an API that accepts IHostedZone.

Can you share the code that you’re trying to write and use. Assuming it was defined, you’re still attempting to assign a list of strings to the value property to your output which only allows type string.

something like the following is what you’d want to do - sketch

const hostedZone = new r53.HostedZone(this, 'my-hosted-zone', {
  zoneName: 'www.shivexample.com',
});

if (hostedZone.hostedZoneNameServers) {
  new cdk.CfnOutput(this, 'MyOutput', {
    value: Fn.join(',', hostedZone.hostedZoneNameServers),
  });
}

let me know how it goes!

Yes you’re right ! It’s working with your proposal; many thanks.

So, now to be perfect, we need to have the capability to get CloudFormation Outputs between accounts; because actually, I’ve to get the output from a file in the Repo. So it means that the “Builder” (another one than me) have to launch CDK with the correct option (that implies that the entire code can’t be valid until prerequisites resources & outputs are created. So, some snippets have to be comment…).
