Describe the Bug

These 2 tests are failing on main branch:

astro/packages/integrations/vercel/test/serverless-prerender.test.js

Line 21 in e22be22

it('outDir is tree-shaken if not needed', async () => {

✖ outDir is tree-shaken if not needed (1.72359ms)
  TypeError [Error]: Cannot read properties of undefined (reading 'replace')

      at async Test.run (node:internal/test_runner/test:574:9)
      at async Suite.processPendingSubtests (node:internal/test_runner/test:318:7)

This one only fails on my WSL (Ubuntu 22.04) setup:

astro/packages/astro/test/ssr-error-pages.test.js

Line 137 in 0626234

it('renders 404 page when a route does not match the request', async () => {

✖ renders 404 page when a route does not match the request (1.939176ms)

    generatedMessage: true,
    code: 'ERR_ASSERTION',
    actual: '',
    expected: 'Something went horribly wrong!',
    operator: 'strictEqual'
  }

What's the expected result?

pnpm build && pnpm test should pass.

Everything seems to work for me in local (Node v22.0.0) and on CI. Might've been a fluke or specific to your setup. As long as it works in CI, we're generally okay with things!
