What did you expect to happen?
I expected the client.add() callback to fire.

Are you willing to submit a pull request to fix this bug?
It is simple enough for anyone to reproduce.

Working with latest from https://cdn.jsdelivr.net/npm/webtorrent@latest/webtorrent.min.js

... which turns out to be 1.9.7.

Below example using version 2.0.5 from the dist folder gives the error stated in the original post.

I used npm to install webtorrent to a temp nodejs project and took the webtorrent.min.js out of there which is version 2.0.15. That version works with my example.
