Describe the Bug

I'm migrating a Cloudflare Pages project to Workers. In my new wrangler.jsonc config, I've declared the same domains that were previously used (and are still managed) by the old Pages app.

When I run wrangler deploy, it fails with:

Hostname 'example.com' already has externally managed DNS records (A, CNAME, etc). Either delete them, try a different hostname, or use the option 'override_existing_dns_record' to override. [code: 100117]

However:

• Wrangler doesn’t expose any way to set override_existing_dns_record via the CLI or config.
• The code in publishCustomDomains suggests an interactive prompt should appear in case of DNS conflicts, but I don’t get one.
• I cloned the repo and hardcoded override_existing_dns_record: true, but the deploy still fails with the same error.

It seems like the flag has no effect at all, and there's currently no way to override existing DNS records during deploy, even though the error message suggests it's possible.

Please provide any relevant error logs
