Reproduction Example/SDK Setup

Hi! I'm trying to upgrade the Astro integration from 7.119.2 to 8.34.0 (also tried from 7.119.2 to 8.0.0 and same). I've tried to create a minimal reproduction to isolate this issue, but I can't manage to reproduce the error in a brand new project. I apogolize about this, I know it sucks as a maintainer not to get a minimal repro.

So this issue is first to ask for clues to debug the error, and 2nd to provide a proper minimal reproduction after debugging. There's one related issue at #13304 for Nuxt but it seems unrelated to my setup.

The issue occurs with a minimal setup, ie. pnpm astro add @sentry/astro:

export default defineConfig({
	output: 'server',
	adapter: netlify(),
	integrations: [sentry({ dsn: process.env.SENTRY_DSN })]
})

The error goes away if I remove sentry from the integrations array.

Steps to Reproduce

1. Start the dev server with astro dev

Expected Result

The page should load properly

Actual Result

I get the following error:
