I'm importing another file with import { test } from "@/stuff". If I don't use the @ path alias and instead do import { test } from "./stuff" then it works fine. Previously the tsconfig-paths module has worked fine for me, but in this ESM project it seems to not work. Any ideas that don't require abandoning ESM and going back to CJS?
