DNSValidatedCertificate: DomainName 64 char cap when creating from CDK but valid when doing so from aws console

[pedrettin]

I encountered an issue building my CDK packages letting me know that the domain name I used to create a Certificate in cdk can not be more than 64chars long. I also found this original github request that explains this is a hard limit on domain verified certificates comes from an RFC standard.

I am confused then at why i can create a certificate for a domain name that is longer than 64 chars when i do so from Certificate Manager in the AWS console.

This is the code that fails in CDK:

new Certificate(this, `${id}-tls-certificate`, {
        "domainName": "*.long.name.of.domain.com",
        "validation": CertificateValidation.fromDns(this.props.hostedZone),
});

and i get this error when i build the package

Error: Domain name must be 64 characters or less
    at new Certificate (/workplace/pedretti/Bowser/src/BowserSearchServiceInfra/node_modules/aws-cdk-lib/aws-certificatemanager/lib/certificate.js:1:2127)

Not sure why there would be such a limit when I can create DNS record longer than that, but if there is a limit, then i'd expect to have the same limit in the console.
