Describe the Bug
What happens
After upgrade to 6.5.0 (also for 6.5.1) all requests to Astro fail due to unhandled exception. I narrowed it down to Netlify Edge Functions. No issue with the edge function code. Even simple set header edge function eventually fails.

Hint:
Make sure your promises all have an `await` or a `.catch()` handler.
How I use Netlify with Astro
I run netlify-cli commands on demand. For example, to serve functions. It forwards requests to netlify servers, though I agree it's a bit cumbersome.
As far as I understand, Astro is trying to improve the DX. But, there are too many moving parts here, it should be at least v7. So folks know it's not a minor version bump.
Reproduction note
Edge functions fail to start due to the issue with fetch. Then Astro skips it and web app still works. My issue occurs when edge functions start. How do I start edge functions in stackblitz? I'm pretty sure it's reproducible.
Temporary solution
Downgrade to v6.4.0
Conclusion
I have an impression you are trying to make netlify adapter way smarter (and complex) it should be in dev mode.
What's the expected result?
Edge Functions work with Astro Netlify adapter
