This is not directly a Luminus question, but I know that @yogthos might have a solution or a better way of doing this.

I also tried a figwheel component following [this](https://practicalli.github.io/clojurescript/figwheel/scripting-with-component.html) and adding it to the system which does load figwheel with the system but cljsbuild throws the same exception upon compiling.

solved... solution in (https://www.reddit.com/r/Clojure/comments/a56tu3/cljsbuild_refuses_to_compile_only_when_using/) if anyone is interested.
