Laravel + websockets: Unhandled promise rejection with TypeError

[ryanbaldisco]

I recently updated my laravel project from (laravel/framework) 10.0 to 10.18, as well as all of my packages. Everything was updated smoothly without errors or warnings. However, when I tried to run the websockets server php artisan websockets:serve I got this error below.

Unhandled promise rejection with TypeError: React\Http\Io\ClientRequestStream::closeError(): Argument #1 ($error) must be of type Exception, Error given, called in /path/to/laravel/vendor/react/promise/src/Internal/RejectedPromise.php on line 73 in /path/to/laravel/vendor/react/http/src/Io/ClientRequestStream.php:238

I tried debugging for hours, but had no luck.
Please, can anyone help me with this? or at least point me to the right direction.

PHP version 8.2.5
Composer version 2.5.8

Stack trace:

Hey @ryanbaldisco, thanks for bringing this up 👍

You're seeing this message because of our Promise v3 release back in July of 2023 last year. I don't think this is a bug in our HTTP component, seems more like something that should be reported in https://github.com/beyondcode/laravel-websockets, as they're throwing an error where only exceptions are allowed for our error events. Although I'm not sure how relevant this currently is, as the project has been archived on 2024-02-07. Laravel reverb seems to be the suggested replacement for this, which also builds on top of ReactPHP.

We could use a Throwable to support both exceptions and errors, as #506 also suggests, but this doesn't work with older PHP versions and will ultimately be a BC break. For v1 we're still supporting these older PHP versions, which will change with ReactPHP v3 (PHP 7.1+). With v3, we want to improve error reporting anyways, so this might be a thing of the past once the next major version is released.

I believe this should answer your question, so I will close this ticket for now. We can reopen this if we can actually prove that this is a bug in this component. If you do need to reopen the ticket, please provide any new findings 👍
