deno: 404 when importing type declaration files from pika.dev using Deno 1.0.2

I have the following source code:

import * as pkg from 'https://cdn.pika.dev/node-fetch/^2.6.0';
console.log('PACKAGE:', pkg);

Running on latest (1.0.2) yields:

deno --version
deno 1.0.2
v8 8.4.300
typescript 3.9.2

deno run --reload <above_test>

FYI, the http and url packages do not exist on pika.dev. It seems like the request tries to get type definitions for all sub-dependencies, but fails if they do not exist.
