I've removed nix from my reflex project, having replaced it with stack. Everything is good, except being able to use the repl. I've tried to create a minimal reflex project to demonstrate what I have tried, and the errors my attempt produces.

The clue to the answer came from this project, https://github.com/nomeata/reflex-dom-fragment-shader-canvas.
Specifically, this flag: package reflex-dom
flags: +use-warp -webkit2gtk
.
I have updated the git project above to reflect a working stack.yaml file.
