Custom Domain seems to behave differently.

I am trying to enable a custom domain on Workers, which works fine (DNS-wise). But when I open the URL I get a 500 internal server error for the custom domain, but not for the workers.dev domain, which works as intened. For confidential reasons, I cannot share the URL. The worker applications connects to a headless cms, using graphql and server side fetch. Environment is exactly the same, so I guess my question would be if there is anything that behaves differently behind a custom domain instead of the workers.dev domain? Something that would cause certain fetch actions to behave differently which might cause the errors?...

metroCode undefined

I'm having an issue with the metro code being undefined (request.cf.metroCode). I've cloned and uploaded https://github.com/cloudflare/docs-examples/tree/main/workers/geolocation-hello-world as is, and no matter what ip address i've tested with, it's always undefined. I can confirm that maxmind has the correct data for the tested ip addresses. Is there anything that I'm missing that needs to be defined within wrangler.jsonc to enable this? Or am I missing something that's absent from the example?...

How to purge cache for workers.dev?

I have a worker that is currently under development and only available via *.workers.dev, not connected to a domain. I am trying to purge cached content for it but have not been successful. The worker makes basic fetch() calls to origin that (seem) to get cached. There is nothing in the Cloudflare Dashboard that I could find (only the cache purge for domains which this worker is not)....

Wrangler is trying to bundle 'fs'. Why? even if I excluded it.

So i am using sveltekit template with to develop app for workers. One of my packages has required('fs') but it is false-positive. I tried to exclude it from vite build by using: ``` fs: fileURLToPath(new URL('./src/empty-module.js', import.meta.url)), path: fileURLToPath(new URL('./src/empty-module.js', import.meta.url)), os: fileURLToPath(new URL('./src/empty-module.js', import.meta.url))...

Cloudflare Pages - Server error (5XX) in Google Search Console

Hi folks, i'm running on Cloudflare Pages with static Astro.dev page from Github pipeline and this started to happend in Google Search Console couple of weeks ago. Some of the pages throw "Server error (5XX)". Nothing in Cloudflare settings seems to be visible / no allerts. It's hard to identify what is blocking Google Crawler to request pages. Pages are indexed in Google and after inspecting via Google Search Console they response properly...

Image binding CPU Time

Hello, I have a worker that's using R2 and Images bindings to composite a single image from layers. Previously this was all done with a sub request to the image transform via url and I had very little CPU time but I wasn't able to test the transforms using the preview URL so switched to bindings. Is the Images binding and transform/output calls whats contributing to my CPU time? I would have thought that would be just wall time? Is there a way this can be made more efficient?...

"internal error" error while using service binding.

Hi, I have two workers. One worker (Worker A) is trying to make an API call to another worker (Worker B). I have enabled the service binding where I have bound Worker A with Worker B, and when I'm trying to call the API, I'm getting this error log in Worker B: internal error; reference = 01d9n3paq7mnnnamd35rml8p. This is how I'm calling the API: await env.data_injection_worker.fetch(aktoReq);....

Custom Headers with Worker Fetch

I'm trying to interact with the Walmart API using fetch from a Queue consumer. The API requires I provide some custom headers which are not x-prefixed. It seems that Cloudflare's fetch strips these headers. Is there some way I can avoid this? Thanks!
