`+server.ts` route inside `.well-known` is not type-checked

[timephy]

Describe the bug

I have a +server.ts file here src/routes/(search_engines)/.well-known/assetlinks.json/+server.ts.

It's contents are not correctly typechecked.
Neither by my LSP, nor by pnpm run check.

---

As you can see inside my editor it does not interpret the contents correctly. Which is weird, because inside the "neighbouring file" src/routes/(search_engines)/robots.txt/+server.ts everything is typechecked as expected.

Not only imports are affected, but also pain syntax errors, such as using a variable that was never defined.

serious, but I can work around it

This is fixed when removing the dot in .well-known.
While that makes type-checking work, it is of course not viable, because the dot is required.

You could use reroute for a temporary workaround

This is already described in the docs: https://svelte.dev/docs/kit/advanced-routing#Encoding

Fixed by encoding the dot.

Hey!
Thanks for the quick response/help!
Encoding fixed the problem 👍🏽

(I think this should still be changed/fixed)
