Error: expected type to be one of ["advanced"], got universal

Steps to reproduce

We're running multiple Partial DNS zones.

Previously, when you created a proxied record, it immediately issued the appropriate certificate automatically without further validation. This worked since the zone itself was ownership validated and Cloudflare found this sufficient proof of ownership.

Issue 1

Now when creating a cloudflare_record, the universal certificate will be created with http validation as default and no option to override. This happens automatically on creation of the record resource.

This is no concern, when the record pointing to Cloudflare is created first. As outlined in the documentation, the certificate will be issued after a brief downtime since Cloudflare can serve the necessary validation http request automatically.

But this does not work when a record is created first in Cloudflare to avoid the mentioned downtime and allow for a zero impact migration.

Issue 2

The attempted workaround to this, was to mange the certificate through a cloudflare_certificate_pack resource. But this does not support universal certificates and would require the issuance of an advanced certificate which are quota'd.

So the only options right now for such a zero downtime migration are either to extract the validation url and content to serve it through the live host or to manually send a PATCH request to change the validation method of the universal certificate.

Issue 3

The third issue is therefore, that you can not access universal certificates through terraform in order to extract the needed validation url and content to serve it elsewhere.

In any case it's not possible to do this natively with terraform and would require manual intervention.

Thank you for reporting this issue! For maintainers to dig into issues it is required that all issues include the entirety of TF_LOG=DEBUG output to be provided. The only parts that should be redacted are your user credentials in the X-Auth-Key, X-Auth-Email and Authorization HTTP headers. Details such as zone or account identifiers are not considered sensitive but can be redacted if you are very cautious. This log file provides additional context from Terraform, the provider and the Cloudflare API that helps in debugging issues. Without it, maintainers are very limited in what they can do and may hamper diagnosis efforts.

This issue has been marked with triage/needs-information and is unlikely to receive maintainer attention until the log file is provided making this a complete bug report.
