What is the issue or error you’re encountering

After a routine automated deployment to update sitemaps I found that all non-static pages (Edge function routes) returned a 500 error this morning. No changes had been made to the site code.

What steps have you taken to resolve the issue?

Checked the API/backend. All working fine and no errors on logs
Rolled back to a previous deployment and site is back online
Network tab in Dev Tools shows no activity
Checked build logs - no issues
All static pages (e.g. /about, /tos etc.) all work fine

What are the steps to reproduce the issue?

Build configuration
Build command: npx @cloudflare/next-on-pages@1
Build output: .vercel/output/static
Root directory:
Build comments: Enabled

Sounds like you had some change server side and something broke.
Check the logs: https://dash.cloudflare.com/?to=/:account/pages/view/:pages-project/:pages-deployment/functions

Here are the logs from my last successful deploy (the one I rolled back to): Cloudflare Deploy Log 2024-11-26 · GitHub

And here are the logs from this morning: Cloudflare Deploy Log 2024-12-02 · GitHub

As far as I can tell, they look identical bar @cloudflare/next-on-pages v1.13.5 → @cloudflare/next-on-pages v1.13.6 and wrangler 3.90.0 → wrangler 3.76.0 (older version?)

Have I missed anything else?

You want runtime logs (where it’s failing) not build logs. Go to the link I sent, navigate to your project and latest deployment and you can look at the logs as they come in

Ah thanks, I wasn’t aware of those logs. Here’s the output:

Hi @WalshyMVP, I used the workaround in this thread, and it appears to have worked: Could not resolve "async_hooks" - #18 by Walshy

The thing is that my logs are saying that I was using next-on-pages version 1.13.6, so the problem doesn’t appear to be fixed as that thread suggests.
