What Next version did you use before, was it working?

[himanshu-ntml]

It was running on Next.js 14.2.11, which is the default version when you create a new app following the OpenNext documentation.

I updated it to next 15 by following next docs here is the link

Let me know if you need anything else.

I appreciate all the work you putting into making nextjs compatible with Cloudflare.
