Fetch + service bindings = internal error

colecrouter · December 15, 2022, 8:53pm

I have a worker running, and a pages project that calls that worker through a service binding. When that worker is called (as of a couple days ago) any calls to fetch() throw internal error with no additional stack trace or info. However, when I call that same worker not using a service binding, it works fine.

v Error here
[site] – sb → [worker] – fetch → [other API]
[site] – fetch → [worker] – fetch → [other API]

Sample:

await fetch('https://google.com');

I tried:

I thought maybe the lack of standard headers might’ve been part of the issue, so I copied some headers from a fetch request into the sb request, but that didn’t help.

Can you share your deployment ID please?

499c3e3f-a15b-4e93-8177-258136bffc67

it’s not accessible right now without authentication. I can set up something simple later, if that helps.

I can’t find any deployments with this UUID, what’s the pages.dev?

colecrouter · December 16, 2022, 4:19am

Sorry,
pvp-legacy-api.aoelite.workers dot dev/ ← throwing the error
880414bd.kit-viewer-v2.pages dot dev/4JWJO ← calls above

Same here, simple pages service binding reqwest::get in router throw “internal error”

How old is your deploy? If you redeploy, does it resolve the issue?

katopz · January 12, 2023, 11:36am

Just deploy a sec ago. I redeploy for 10 time today try to figure this out and gave up then i found this issue after search.

cherryjimbo · January 12, 2023, 11:39am

Can you share your pages.dev, a deployment UUID, and your account ID please?

Thanks

Thanks, I’ve passed this along for someone to look at when they are able.

Walshy · January 12, 2023, 12:09pm

I’m unable to see any errors for that account ID on our end and it doesn’t match the account ID for that zone so I’m unable to verify or lookup errors for that owner.

Are you sure they are the right details?

katopz · January 12, 2023, 12:25pm

Not sure this is account id you mean?

This is just now

katopz · January 23, 2023, 10:32am

I filed a bug here, not sure any update on this?

### Which Cloudflare product(s) does this pertain to? Pages ### What version o…f `Wrangler` are you using? 2.8.0 ### What operating system are you using? MacOS ### Describe the Bug ## Bound Worker This Worker is called via Service Bindings. Worker: ```ts // src/index.ts export default <ExportedHandler> { async fetch(req) { await fetch("https://google.com") return new Response("lol") }, }; ``` ## Errors on Functions Functions: ```ts // functions/test.ts interface Environment { SERVICE: Fetcher } export const onRequest: PagesFunction<Environment> = (context) => { return context.env.SERVICE.fetch(context.request); } ``` Tail logs from Worker: ```sh GET https://89fdd660.test-functions-7jm.pages.dev/test - Exception Thrown @ 1/23/2023, 4:08:41 PM ✘ [ERROR] Error: internal error ``` Example URL: https://89fdd660.test-functions-7jm.pages.dev/test ## Works on Workers ```ts // src/index.ts interface Environment { WORKER: Fetcher } export default <ExportedHandler<Environment>> { fetch(req, env) { return env.WORKER.fetch(req) }, }; ``` Example URL: https://test-worker.kianorguk.workers.dev ## Additional info Removing the `fetch` call from the bound Worker stops the error being thrown by Functions.
