Describe the Bug

Observed behavior

When using Wrangler 3.30.1 and attempting to start the worker with wrangler dev, I get the following error:

X [ERROR] Cannot infer host from first route: undefined.

  You can explicitly set the `dev.host` configuration in your wrangler.toml file, for example:

        
        [dev]
        host = "example.com"

This error does not occur if I'm using Wrangler 3.30.0 or lower.

Expected behavior

Since the changelog does not indicate any kind of breaking change, I would expect future versions to continue working.

@Razzmatazzz I'm just looking at this now, but I can't reproduce it with the example you provided. Would it be possible to get a minimal reproduction, so that we can isolate the issue?
