Thanks for the issue @martwozniak 🙂

The issue here is that @cloudflare/next-on-pages generates a Pages project in advanced mode, this mode is incompatible with the functions/ directory implementation and the latter gets ignored, as you can see in the docs:

So it is expected for your implementation not to work, you'll need to change it so that you integrate sentry directly in your Next.js application.

I haven't used sentry before so unfortunately I cannot help you much in that regard, but the sentry docs seem to include clear instructions on how to do so 🙂

Also note that people have had a few issues with sentry (like #178 and #420), so I can't guarantee that it'll work for your specific use case (but I'll be here to help if I can 🙂)

I hope this is helpful 🙂
