Error 1105 on initial request

In the last week, I've started getting Error 1105 on first request to a Pages site backed by a Pages Function. Refreshing usually loads the page. That error isn't documented. Any ideas how to diagnose this? In the Pages Functions log, the request shows as canceled.

Sourcemapped stacktraces in the dev console

Does anyone have sourcemaps working in dev in the console? My workers mainly run off queues (so no HTTP response to display). I've gone down some rabbit trails with miniflare, Stacktracery, etc. trying to see if there's a way to translate console logs to original Typescript sources, but no success yet.

Long-running worker performance

I've implemented a background sync worker, triggered by a queue. It calls an external, paginated API (dozens of sub-requests) and performs 100s of SQL queries using the socket API. This works wonderfully, but it's very slow. Where a local execution might take 2-3 seconds, in production it takes over 60. Some syncs are ~5 minutes. Any tips on how to diagnose the slowdown in production, or where to look to optimize? Off the top of my head, the source could be: 1. Roundtrips to/from the DB server (which is local in dev, and supabase.co in prod) 2. Worker CPU speed (don't think I'm doing anything too CPU intensive, but there is some list processing) 3. Sub-request (or socket) latencies

Skipping a module when bundling

Has anyone found a way to skip a module dependancy when bundling? I'm using googleapis, which has a require('http2') while http2 isn't available in the runtime. That might be fine -- I think I can pass runtime options to avoid using it. I just need to find a way to get esbuild to ignore the missing dependancy.

Debugging Remix server-side 500s

After pushing a change to a Remix app to Pages + Functions, I'm getting 500 errors in the browser, but Cloudflare Pages Functions logs show "successful" requests. How do I get the underlying error?
