Operating System: Linux
Node Version: v14.20.0
Nuxt Version: 3.0.0-rc.6
Package Manager: yarn@1.22.19
Builder: vite
User Config: srcDir, meta, loading, build, modules, tailwindcss, vite

Reproduction

Install nuxt test utils and vitest

yarn add --dev @nuxt/test-utils-edge vitest

Define the nuxt.config.js `//nuxt.config.js import { defineNuxtConfig } from ‘nuxt’

export default defineNuxtConfig({ })`

And create the test file `//test/index.test.js import { $fetch, createTest } from ‘@nuxt/test-utils-edge’

const test = createTest({ testDir: ‘./src’, rootDir: ‘.’, server: true, browser: true, configFile: ‘./nuxt.config.js’, dev: true }) // WHERE THE ERROR OCCURS await test.setup()

describe(‘landing page test’, async () => { $fetch(‘http://localhost:31300/’)
})`

Execute test by vitest --dir test --run --reporter verbose --globals --config vitest.config.js

Describe the bug

During the test when the code call the “test.setup”, the error below appears:

FATAL ERROR: v8::FromJust Maybe value is Nothing. 1: 0x10d83c0e5 node::Abort() [/usr/local/bin/node] 2: 0x10d83c268 node::OnFatalError(char const*, char const*) [/usr/local/bin/node]

Debugging the code, the error is being throwed by the code below:

//@nuxt/kit/dist/index.mjs async function loadNuxt(opts) { opts.cwd = opts.cwd || opts.rootDir; opts.overrides = opts.overrides || opts.config || {}; const resolveOpts = { paths: opts.cwd }; opts.overrides.dev = !!opts.dev; const nearestNuxtPkg = await Promise.all([“nuxt3”, “nuxt”, “nuxt-edge”].map((pkg2) => resolvePackageJSON(pkg2, { url: opts.cwd }).catch(() => null))).then(® => r.filter(Boolean).sort((a, b) => b.length - a.length)[0]); if (!nearestNuxtPkg) { throw new Error(Cannot find any nuxt version from ${opts.cwd}); } const pkg = await readPackageJSON(nearestNuxtPkg); const majorVersion = parseInt((pkg.version || “”).split(“.”)[0]); if (majorVersion === 3) { //Can’t load nuxt for some reason const { loadNuxt: loadNuxt3 } = await importModule(pkg._name || pkg.name, resolveOpts); const nuxt2 = await loadNuxt3(opts); return nuxt2; } const { loadNuxt: loadNuxt2 } = await tryImportModule(“nuxt-edge”, resolveOpts) || await importModule(“nuxt”, resolveOpts); const nuxt = await loadNuxt2({ rootDir: opts.cwd, for: opts.dev ? “dev” : “build”, configOverrides: opts.overrides, ready: opts.ready, envConfig: opts.dotenv }); return nuxt; }
