I'm struggling to get vim-fireplace (through cider-nrepl) working on a boot project, but I'm finding conflicting examples for how to configure it, and get errors both ways.

following this https://github.com/clojure-emacs/cider-nrepl#via-boot I get

following the first example here https://github.com/boot-clj/boot/wiki/Cider-REPL I get https://pastebin.com/ihGsU0ki when I try to evaluate something.

that latter error looks like things are connecting, but fireplace and nrepl are speaking different dialects?

braden.shepherdson02:07:51

if I drop the *default-middleware* call from that latter guide, I get

{'status': ['eval-error', 'done'], 'id': 'fireplace-archlinux-1562898025-39', 'out': '             ^[[1;31mjava.lang.RuntimeException^[[m: ^[[3mUnable to resolve symbol: let

discovered a workaround: use Clojure 1.9.0, not 1.10.1. not satisfying, but it'll do for now.
