I am trying to run the guestbook-postgres of the Web Development with Clojure, 3rd edition. When I run shadow-cljs I get

$ npx shadow-cljs watch app
shadow-cljs - config: /Users/riccardotacconi/dev/clojure/code/guestbook-postgres/shadow-cljs.edn  cli version: 2.8.52  node: v14.16.0
shadow-cljs - running: lein run -m shadow.cljs.devtools.cli --npm watch app
