Clojurians Log v2

Hi, I’m configuring the polylith-kaocha wrapper, following the instructions on https://github.com/imrekoszo/polylith-kaocha. However, when I run clojure -M:poly test :verbose , I get the following error:

ERROR in unit (load.clj:48)

Hi, I'm having difficulty attempting to implement the same interface in multiple components (only one of which is included in any given project), but poly info is giving me an error that makes it look as if because I have it included in one component not declared as a dependency of one of the projects it can't find the same namespace as defined in the component actually defined as a dependency of the project. I've checked and the signatures are 100% identical - not sure what I'm doing wrong here, as the poly documentation seems to indicate I should be able to do this.
