For anyone interested, I was able to solve this problem. See my other post here: https://clojurians.slack.com/archives/C0744GXCJ/p1599585011046500
Curious anyone know what this error is ? I get it in all project but it seems to do no harm but it is a tad annoying
@oliver.marks I saw that most when we worked together :) I think I see it on page hard reload too.
