`wrangler pages dev` 404s some functions/routes

functions/index.ts and functions/*/index.ts , functions/_middleware.ts and functions/*/_middleware.ts work, but nothing else. For example, functions/*/*/index.ts does not work. Parameterized paths also don’t work.

I’m on Windows. To repro, open new folder, npm init, npm i wrangler@alpha, create functions folder, create index.ts, insert:

export const onRequestGet: PagesFunction<{}> = async ({ request, env }): Promise<Response> => {
    return new Response("hello1", { status: 200 })
}

Run npx wrangler pages dev ./. Move it to functions/index.ts, http://localhost:8788/ works fine. Move it to functions/test/test/index.ts, http://localhost:8788/test/test/ returns a 404.

The other day, this was happening both when building on Cf and when I tried using wrangler pages dev. Now it’s just happening with wrangler. This seems like an isolated case, so let me know if there’s any more info I can provide.

Should have put my comment here. It’s a bug in the code generator:

It seems as though that PR (or another one from 0.0.16) introduced a bug where the “route deduplication” is disregarding methods. This doesn’t seem like it would be a Windows exclusive issue, but I’ve gone ahead and made another PR #465.
