Start with the repro files deps.edn, tests.edn, and test/repro/core_test.cljs. Run the documented clojure -A:test -m kaocha.runner --no-capture-output command and inspect the ClojureScript test runner entry point indicated by the stack trace. Done means the namespace is resolved and the example test runs without the reported exception.
