Can't run with clojure 1.9.0

[rrrnld]

Trying to run a project with chord (server-side) gives me the following error:

$ lein run

What helped was this comment that suggested downgrading Clojure, so I'm sticking with 1.8.0 for now.

[fmnoise]

Upgrading to latest core.async helps, but I'm not sure things are still working as expected, @heyarne probably you can test locally on your project

[jarohen]

Sorry @heyarne, I missed this issue :( It's been a while since I've done a Chord release so I'll release one with bumped dependencies, see if that helps.

I doubt the problem is within Chord itself - I couldn't find an explicit refer-clojure call anywhere in the codebase.

[fmnoise]

@jarohen problem is with core.async, upgrading it to recent version helps
