Hello. I have a figwheel-main project, which uses React (and some UI libraries) from :foreign-libs . When I made a copy of it (need to turn it in a similar project), in one way or another I've started receiveing an error Uncaught TypeError: Cannot read property 'render' of undefined with no possible way to fix. I tried to create new reagent project (`lein new figwheel-main hello-world.core -- +npm-bundle --reagent`) and take core.cljsfile from there, but this didn't help either
