Vite adapter causes development server to throw on launch

Tried spinning up a quick Vite/Vue project this morning and found that the Netlify adapter was throwing an error when using the dev server:

error: unexpected argument '--allow-scripts' found
file:///Users/.../node_modules/.pnpm/@netlify+edge-functions-dev@2.0.1/node_modules/@netlify/edge-functions-dev/dist/node/main.js:317
        throw new Error("Could not establish a connection to the Netlify Edge Functions local development server");
              ^

Error: Could not establish a connection to the Netlify Edge Functions local development server

I've got a minimum viable replication of a project that causes the issue linked below. It looks to be isolated to the edge functions local development server, as switching that feature off causes the dev server to launch successfully.

I also noticed this happening on an Astro project. I did not have this issue with the Astro Netlify adapter when I last spun up that project locally two weeks ago, which could suggest a recent regression.

• OS: MacOS 26.5.2, M2 Processor (also replicated on an M2 Pro)
• Node: 26.8.2
• Tested with package managers:
  • pnpm: 12.3.4
  • npm: 11.19.1 (should really update that, whoops)

Let me know if you need any more details!

Start with the linked Vite/Vue reproduction and the adapter's edge-functions local development server, focusing on the launch path that passes the unsupported --allow-scripts argument. Compare the Vite and Astro adapter behavior around that server startup. Done means the development server launches successfully with edge functions enabled in the reproduction.
