Does not work in Deno (TypeError on every request)

[Pyroglyph]

Simple usage does not work at all in Deno. Every request ends in the same TypeError.

Example using PokeAPI:

// cors.ts
import corsProxy from 'npm:cors-anywhere';
corsProxy.createServer().listen(8080, 'localhost', () => {
    console.log('Running CORS Anywhere');
    fetch('http://localhost:8080/pokeapi.co:443/api/v2/');
});

Result:

❯ deno run --allow-net cors.ts
Running CORS Anywhere
TypeError: Cannot read properties of undefined (reading 'encrypted')
    at ServerImpl.<anonymous> (file:///home/pyro/.cache/deno/npm/registry.npmjs.org/cors-anywhere/0.4.4/lib/cors-anywhere.js:384:47)
    at ServerImpl.emit (https://deno.land/std@0.177.0/node/_events.mjs:379:28)

Not even the sample URLs given in the readme work. Navigating to / works if you launch Deno with --allow-read, and so does /iscorsneeded. Nothing else works though.

After more investigating, it appears that the connection property is not present on req when this is run through Deno.

Simply changing this line

var isRequestedOverHttps = req.connection.encrypted || /^\s*https/.test(req.headers['x-forwarded-proto']);

to this

var isRequestedOverHttps = req.connection?.encrypted || /^\s*https/.test(req.headers['x-forwarded-proto']);
                                         ^

should solve the issue.
