🐛 BUG: Uncaught exception

eloff commented 1 year ago

Which Cloudflare product(s) does this pertain to?

Wrangler or miniflare

What version(s) of the tool(s) are you using?

3.5.0

What version of Node are you using?

18.16.1

What operating system are you using?

Linux (Ubuntu 20.04)

Describe the Bug

In one of my handlers, after executing a select query with batch, I get the following exception:

workerd/server/server.c++:2533: error: Uncaught exception: kj/async-io-unix.c++:186: disconnected: remote.worker_do_not_log; Request failed due to internal error

It seems it's in some kind of destructor or finalizer or other thread / cleanup task, since execution continues after the query, because I can see console.log output from subsequent code. However, the server crashes before it is able to return the response (client doesn't get a response back.) I can reproduce this every single run. Commenting out that query makes the exception go away. No other queries are executed in that request.

I deleted, the database, deleted .wrangler dir, and recreated the database. Same issue.

I created a new hello world project (following the getting started guide), containing only the "hello world" response and got the same exception on the first run only. Subsequent runs were fine. That's interesting, what state could wrangler be keeping that's the same for the machine, but not in the directory/project/code which all changed?

I switched back to the original project, reproduced the exception again. Went back to the new hello world, but it's fine now, I can't reproduce the exception in the hello world project again. Odd.

I then added the same database, same migrations, same query to the hello world project. No issues. I don't know how to make a minimal repro for it.

edit: I tried again this morning, after rebooting overnight. The error is gone, the reboot fixed it. It wasn't the query at fault here, probably not d1 (directly anyway). There's something else going on, and somehow a reboot fixed it.

It's tough to debug a problem with so little to go on. Is there anything I can do to get more info? Is there a way to build a debug version of wrangler or miniflare? Enable logging?

Please provide a link to a minimal reproduction

No response

Please provide any relevant error logs

No response

i get the identical error in my workers project, and i don't use d3. running on macOS 13.5 with wrangler 3.5.0. also filed here: https://github.com/cloudflare/workerd/issues/1010

I'm having the same issue:

chitalian commented 1 year ago

I am getting this issue when quickly closing a connection to my worker

penalosa commented 1 year ago

I've transferred this to workerd since it looks like it's an error log coming from workerd rather than Wrangler directly

jasnell commented 11 months ago

We'll need a simple reproduction example in order to diagnose this.

SyntaxColoring commented 10 months ago

I'm not sure if this is exactly the same thing:

workerd/server/server.c++:3069: error: Uncaught exception: kj/compat/http.c++:3939: disconnected: worker_do_not_log; Request failed due to internal error

(Note kj/compat/http.c++:3939 instead of kj/async-io-unix.c++:186, which the OP reported.)

@jasnell I can reproduce this, but sometimes it requires patience.

Clone https://github.com/SyntaxColoring/cloudflare-crash-repro.
npm install && npm run dev.
In something like Postman, open a bunch of concurrent WebSocket connections to localhost:8787. I opened a few to localhost:8787 and a few to localhost:8787/some/other/path.
Send a few messages on each connection.
Wait a few minutes. The error will probably happen on its own. Some (but not necessarily all?) of the WebSocket connections will disconnect. If it doesn't happen after a few minutes, send some more WebSocket messages and wait some more.

Here are the associated log files from one reproduction.

gaberogan commented 9 months ago

I was able to reproduce this using a bare minimum worker template with fetch('https://example.com').

Strangely it seems to work fine with fetch('http://ip-api.com/json'), so I think it's an issue with SSL.

Here is the reproduction: https://github.com/cloudflare/workers-sdk/files/14214588/test-worker.zip

I am using wrangler 3.28.0 and macOS 13.5 and node.js 18, but I don't think this matters because I've experienced this reliably on both my windows and mac computers, with different sdk versions and different node.js versions

Last week I was not experiencing this and I have no idea why..

gaberogan commented 9 months ago

Can we please rename this issue to something more useful? Like "internal error" on fetch with HTTPS

akainocode commented 6 months ago

I would like to confirm this issue, but it seemed to resolve with a restart of my machine.

I am currently using WSL2 though, that might have an affect on it but above people have mentioned that it happens regardless of OS.

robmv commented 6 months ago

We'll need a simple reproduction example in order to diagnose this.

I am new to Cloudfare Workers, so I am starting the Rust example project, so I think I have the simplest reproduction:

Install the Rust example npx wrangler generate hello-world-rust https://github.com/cloudflare/workers-sdk/templates/experimental/worker-rust
Run npx wrangler dev
Open the example on the browser with [b] option.
When you get the Hello, World! output, just press Control+R to reload the browser without releasing the keys in order to reload indefinitely.

The same error presented here, with different line number, maybe it isn ´t the same case but I find it weird that a fast and simple REST endpoint like this could fail so easily.

 [ERROR] workerd/server/server.c++:3340: error: Uncaught exception: kj/async-io-unix.c++:778: disconnected: remote.worker_do_not_log; Request failed due to internal error`

KyGuy2002 commented 6 months ago

I am using playwright testing in github actions and this error is spammed. Doesn't seem to affect the behaviour of the server or success of the tests though, so not a huge deal for me. This also happens when running the tests locally but doesnt happen when running the dev server and using the app normally.

I am running npx wrangler pages dev .vercel/output/static after building the site with npx @cloudflare/next-on-pages@latest. Doesn't work locally or in prod (cf pages) either.

I had the exactly same error with minimal reproduction, based on this tutorial, with Ngrok hosting. https://developers.cloudflare.com/durable-objects/examples/websocket-hibernation-server/

WebSocket handshaking is succeeded, but in a few minutes, connection got lost because of this above error. This error does not appear when I just connect to localhost server. It is only on Ngrok environment.

Any solution?

Any solution?

@HiraiKyo

None that I am aware of sorry, plus this issue seems old, I doubt we are getting any response or solution anytime soon.

kentonv commented 5 months ago

Any time you see "internal error", there should be a separate log line actually logging the real error. You need to look for that log line.

@martian0x80 in your example the actual error seems to be:

failed: DNS lookup failed.; params.host = internal_suspense_cache_hostname.local; params.service = ; gai_strerror(status) = Name or service not known

This seems to be a regular DNS lookup error, probably specific to your environment.

Obviously the way these errors reported is not so great. Sorry about that. workerd's error logging is awkward since the code was originally designed to log errors that we, the Cloudflare Workers team, needed to address, while explicitly not logging problems that the application should address (those are simply delivered to the application as thrown exceptions). We really need to go back and come up with a better story here.

@kentonv Thanks mate, so I cannot get some meaningful log for websocket close :(

Thanks for the response, I just tested it on a new Github Codespace as well and I get the same errors, even on the Cloudflare Pages deployment, which throws a silent "error code: 1016" in the logs, this is what wrangler logs say:

Connected to deployment <deployment-id>, waiting for logs...
GET https://xxxx.pages.dev/ - Ok @ 16/6/2024, 1:19:20 pm
  (error) error code: 1016

  (error) error code: 1016
  (error) error code: 1016

This only occurs on pages that are server side rendered. I have no idea why 'internal_suspense_cache_hostname.local' is not resolved. These are the errors, I have seen so far in the same log (ordered):

✘ [ERROR] workerd/jsg/util.c++:278: error: e = kj/async-io-unix.c++:1298: failed: DNS lookup failed.; params.host = internal_suspense_cache_hostname.local; params.service = ; gai_strerror(status) = Name or service not known
✘ [ERROR] Uncaught (async) Error: internal error
✘ [ERROR] A hanging Promise was canceled. This happens when the worker runtime is waiting for a Promise from JavaScript to resolve, but has detected that the Promise cannot possibly ever resolve because all code and events related to the Promise's I/O context have already finished.
✘ [ERROR] Uncaught (in response) Error: The script will never generate a response.
✘ [ERROR] workerd/server/server.c++:3346: error: Uncaught exception: workerd/io/io-context.c++:1167: failed: remote.jsg.Error: The script will never generate a response.

I wish I could debug this.

I am seeing similar (error) error code: 1016 in my logs. I am fetching a file from r2 with a regular fetch via a cloudflare configured custom domain. All of the DNS settings were setup with cloudflare. It's frustrating how little log information is available.

Is there anything new on this? I have the same error. And there is just the internal error without any other meaningful log. wrangler dev --remote

After removing .next , .vercel and .wrangler directories I was able to stop seeing this error. I had been without running the preview command for a while, so not sure what exactly caused the issue.

I just had this issue and managed to resolve it by using 127.0.0.1 instead of localhost for wrangler. For example by adding the following to wrangler.toml

[dev]
ip = "127.0.0.1"

Seems to be some problem with DNS resolution.. which may explain why it worked for me on one machine and not the other..

In wrangler.toml also worked for me! Thanks!
