Trouble binding subdomain to workers
Hi - I have my domain set up in cloudflare and I would have thought it would be straightforward to bind a trigger to the domain. I have my routes 
  "routes": [
    {
      "pattern": "my-project.my-domain.com/",
      "zone_name": "my-domain.com"
    }
  ],
  "routes": [
    {
      "pattern": "my-project.my-domain.com/",
      "zone_name": "my-domain.com"
    }
  ],
Set up and it appears to be working - no complaints registering that binding. However nslookup my-project.my-domain.com is failing, falling back to my ISP's default page.
Do I need to set up a subdomain in DNS? And if so to what address do I point it? It feels like I shouldn't have to do any of this since the domain is managed by cloudflare DNS, but I might be missing something.
