Hello, I'm getting an NullPointerException when I try to compile my tests. My build config is simply
:test {:target :karma
:test-dir "resources/public/js/karma"}NullPointerException:

(Install karma, create a karma.conf.js, etc)
I used the re-frame template and just reinstalled karma. Still get the NPE 😞
Do you have an url for the template? (And the exact options you've used, if applicable)
From https://shadow-cljs.github.io/docs/UsersGuide.html#_the_build, :output-to is not optional for :karma builds, and the NPE indeed points to that being the case (https://github.com/thheller/shadow-cljs/blob/master/src/main/shadow/build/targets/karma.clj#L23)
