Nextjs Optional Catch-All route at the Root level is intercepting `_vercel/insights/script.js` about analytics

Hey @nautilytics

Are you proxying all traffic from for example /base to the Vercel deployment?
You can just add another proxy for /_vercel/insights/* to the deployment without /base.

We are having this same issue. We have basePath defined in our Next.js app, so we would expect _vercel/insights/script.js to live at /base/path/_vercel/insights/script.js but instead it lives at the root which is routed to a different endpoint by our dynamic router handler.

Hey @Saeris

The issue is that you've most probably not enabled Audiences in the Vercel dashboard before deploying the changes.
The codesandbox can't work because it needs to be hosted on Vercel in order to use Vercel Web Analytics (Audiences) as it uses the proxy /_vercel/insights/

Let me know if that helps!
