Pulling my hair out again. Can't find anything about this error anywhere.

This appears to be an Emacs issue. This was happening with a project so I dropped back to a minimal figwheel-main project, and am still getting the error.

pataprogramming21:01:28

I've axed everything in .lein/profiles.clj, so I know that's not the problem this time.

pataprogramming21:01:09

I say it appears to be an emacs issue because there's no error displayed when starting from the CLI with lein fig:build -- --build dev --repl

But when launching that way, the browser hangs when attempting to go to localhost:9500 in the browser. So there may be something else going on.

I'm at the end of my tether, here, as everything was working swimmingly before I left for vacation, and I didn't change anything meanwhile. So it's something to do with my setup, but everything I've tried so far has been a dead end.

Maybe the clojurescript version is too recent and incompatible, if the demo works try downgrading to the version it uses

pataprogramming23:01:52

Thanks, @jkr.sw, I'll give it a shot

pataprogramming23:01:27

Yep, the demo project works, and downgrading ClojureScript fixes the compiler issue. Thanks.

There's another issue to chase down, but figwheel is building and the browser REPL is connecting again.
