Run time error when admin.npubs is not empty

I've stood up nsecbunkerd the hard way. And I'm encountering:

/home/ubuntu/code/nsecbunkerd/node_modules/nostr-tools/lib/cjs/index.js:1243
  let cryptoKey = await crypto.subtle.importKey("raw", normalizedKey, { name: "AES-CBC" }, false, ["encrypt"]);
                  ^

ReferenceError: crypto is not defined

Node.js v18.19.1

My /config/nsecbunkger.json:

{
  "nostr": {

      "wss://nostr.1661.io",
      "wss://relay.nsecbunker.com"

    }
  },
  "verbose": true,
  "version": "0.10.3"
}

Running on a plain vanilla ubuntu 22.04 LTS, Node v18.19.1

The setting admin.npubs seems to be the main issue. When I set it to [], nsecbunkerd starts up and seems to be working. However, no admin.npubs, no admin. The admin ui at apps.nsecbunkerd.com rightfully won't connect.
