Deno: How to import npm scoped packages with @ in deno?

I am trying to import @whiskeysockets/baileys in deno like this:

import * as a from "npm:@whiskeysockets/baileys";
console.log(a);

But it's showing the following error when I try to run deno run main.ts:
error: Error in @whiskeysockets/baileys@6.6.0 parsing version requirement for dependency: libsignal@github:adiwajshing/libsignal-node

Invalid npm version requirement. Unexpected character.
github:adiwajshing/libsignal-node
~

Caused by:
0: Invalid npm version requirement. Unexpected character.
github:adiwajshing/libsignal-node
~
1: Unexpected character.
github:adiwajshing/libsignal-node

I'm guessing that it's interpreting 'whiskeysockets' as version number instead of the scope namespace since it's followed by '@'? Not sure. How can I fix this and import it properly?
