As far as I can tell, this project doesn't work at all in node 12.
I'm testing with Node 12.18.3 (the current node LTS release), and all HTTP/2 requests are never successfully sent to the server.
Easy to reproduce: npm test for this project fails, with every http2 test timing out.
Any ideas why? Happy to help get this fixed, but pointers in the right direction would be very useful!
