missing .svelte-kit/output/runtime/control.js file causes deno typechecks to fail

[andykais]

Describe the bug

Since upgrading to deno 2, I am getting build failures using sveltekit. This seems to be because an autogenerated file .svelte-kit/output/server/index.js references a non existent file .svelte-kit/output/runtime/control.js (.svelte-kit/output/runtime/ doesnt appear to be a folder at all locally). The exact code referenced in index.js is this:

function normalize_error(error) {
  return (
    /** @type {import('../runtime/control.js').Redirect | HttpError | SvelteKitError | Error} */
    error
  );
}

I will be opening an issue on the deno side since this seems to be a runtime error despite this being a jsdoc comment which is confusing, but there is still something funky about a reference to a non existent file.

Reproduction

repro using this project here https://github.com/andykais/forager/tree/main/web. Steps to repro are below:

git clone git@github.com:andykais/forager.git
cd web
deno install
deno task build

Logs

`deno task build` (`deno run -A --unstable-ffi --check npm:vite build`) will produce the following output:

actually it looks like this issue is already known on the deno side denoland/deno#26155. It sounds like the consensus is that deno is doing the "correct" thing when disabling typechecking. I think deno could be more lenient on these deep library errors, but I would still push that fixing this incorrect typing on the sveltekit side would unblock a lot of deno + sveltekit users

Please provide a minimal reproduction instead of a link to your project.

Sure. This has a paired down version of the issue https://github.com/andykais/sveltekit-deno-build-bug-repro. I needed to include my custom deno adapter mainly just because I need to trigger the vite build to actually output the sveltekit files. The adapter code has been paired down as well.

I attached a bit more info on the bug. If its helpful, I can separate the commits between what sv create generates and the changes I needed to make to recreate the bug afterwards too

I'm unable to reproduce the issue with the given reproduction. Below are the full logs / commands I've used. Note: I had to specifically run deno install --allow-scripts=npm:@sveltejs/kit@2.8.0 to get the npm postInstall script to run.
