Describe the bug
In version 2.20.0, using adapter-vercel with the runtime: 'edge' option, the build fails with the following error:
Top-level await is not available in the configured target environment ("es2020")
Reproduction
Go to https://stackblitz.com/edit/sveltejs-kit-template-default-t41fd9vn?description=The%20default%20SvelteKit%20template,%20generated%20with%20create-svelte&file=svelte.config.js&title=SvelteKit%20Default%20Template and run npm run build.
Removing runtime: 'edge' fixes it, as well as reverting to sveltekit version 2.19.2.
