Describe the Bug

Reproduction:

1. Using command pnpm create astro --template starlight to create new project, select Write TypeScript.
2. Build using pnpm run build, then failed, error location is src/content/config.ts line 5
3. Select JS has no build problem.

Sorry, I do not know how to create a starlight project using stackblitz, and how to run build command in it. So the project in it is a default astro basic project, just for submit the issue.

Thanks for your report 🙌

I can repro the issue on my end with the latest version of Astro (v4.3.3). As a temporary workaround, rolling back to Astro v4.3.2 seems to fix the issue.

I did not yet have the time to investigate but by quickly looking at the changelog, #9906 seems to be the only related change.

Likely caused by my PR as you said. I wonder if this error is only in starlight (hence caused by Starlight importing some types that changed) or if it also happens in standard astro projects

Thanks for the report @mj8327! I think this will need fixing upstream in astro so transferring this issue there.

Thanks a lot for the quick fix. I was bitten by this today and it's nice to see a PR with a fix already 🧡
