Describe the Bug

---
const route = '/page-a';
return Astro.redirect(route, 307);

Hello world!

Gives this error when using @astrojs/check:

src/pages/index.astro:4:7 - error ts(6133): 'route' is declared but its value is never read.

4 const route = '/page-a';
        ~~~~~

What's the expected result?

To not get this TS warning. I'm using strictest tsconfig which means this is an error and it prevents me from running astro build unless I'm disabling TS checks.

(open new terminal and type npx astro check)
