Panic output

No response

Expected output

Terraform should create the CRON Trigger without problems.

Actual output

Creation failed with workers.api.error.subdomain_required

Steps to reproduce

Create a new Cloudflare Account
terraform init
terraform apply

Additional factoids

This problem only happens with new Cloudflare Accounts (Hasn't setup any Workers before, without setting up a Worker domain)

There seems to be an inconsistency in the behavior of the API: if a Cloudflare account has never created any Workers, a newly created Worker by Terraform will not be able to set the CRON Trigger due to the above error
