Hostname already has externally managed DNS records, use 'override_existing_dns_record' to override?

I'm getting the following error:
Hostname 'mysiteredacted.org.country' 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]

If you think this is a bug, please open an issue at: https://github.com/cloudflare/workers-sdk/issues/new/choose

The website is externally paid for on Freeparking, but I've added it to Cloudflare and it shows as active - I added both Cloudflare nameservers to freeparking, and removed all the old A/AAAA/CNAME/TXT records from Freeparking and Cloudflare, then added my own A record pointing to 192.0.2.1. Here's my wrangler.jsonc:
