`wrangler dev` fails when zone has no apex record

[Electroid]

🐛 Bug report

Describe the bug

If a zone has no apex record, when running wrangler dev, the following error shows up:

Error: error sending request for url (https://<zone>/cdn-cgi/workers/preview/?s0=<token>): error trying to connect: dns error: failed to lookup address information: nodename nor servname provided, or not known

Reproduce the bug

A list of steps to reproduce the bug.

1. Either create a new zone, or remove all DNS records from an existing zone
2. Generate a wrangler template, and specify any route to the zone
3. Run wrangler dev
4. See the error

Expected behavior

Wrangler should instruct the developer to ensure an apex record exists on their zone.

Environment and versions

Fill out the following information about your environment.

• operating system: macOS Big Sur
• output of wrangler -V: wrangler 1.11.0
• output of node -v: v15.4.0
• content of wrangler.toml:

name = "gamertag"
type = "javascript"
account_id = "..."
zone_id = "..."
workers_dev = false
routes = ["api.gamertag.dev/random"]

Note: There is a DNS record for api.gamertag.dev, but no record for gamertag.dev

seeing that right now with my first wrangler rodeo. 👍

Yes, facing same. Feels strange to require have apex record just to run wrangler dev.

Update: still seeing with 1.17:

% wrangler -V
wrangler 1.17.0
