Nextcloud 27 - psr/Log issue

[dico-hubnc]

Hello,

I've got a new Debian 12 with fresh Nextcloud 27.0.2 installed on a VPS (PHP 8.2 as default).
When I put the 'auto prepend' in my apache VirtualHost file, I get HTTP 500 Error on each http request.

In /var/log/apache2/nextcloud.error.log :
[php:error] [pid 14186] [client IPxxxxx:53046] PHP Fatal error: Declaration of OC\Log\PsrLoggerAdapter::alert($message, array $context = []) must be compatible with Psr\Log\LoggerInterface::alert(Stringable|string $message, array $context = []): void in /var/www/nextcloud/lib/private/Log/PsrLoggerAdapter.php on line 87

Is there an incompatibility between Nextcloud and this bouncer ?
Is there a workaround to have this working ?

Many thanks,
Dicohub

Hi @dico-hubnc,
I was able to reproduce the bug.

Nextcloud sources includes a 1.1.4 version of the psr/log package (https://github.com/nextcloud/3rdparty/blob/7293b4ffe86c0b48c3172bd8f180a12e0907fd60/composer.lock#L3412)

The standalone bouncer depends on psr/log too. But, during installation, composer picks up the highest compatible version available. With php 8.2, it is 3.0.0.

As we are using the auto_prepend_file mechanism, it ends with the incompatibility issue you reported (because there are 2 different and incompatible versions of the same package that are loaded together).

For the standalone bouncer to work here, we have to downgrade its version of psr/log.

If you followed the installation guide, it can be done by running the following command from the source folder of the bouncer (/path/to/the/crowdsec-standalone-bouncer in the installation guide):

composer update --with psr/log:1.1.4

Please let me know if it solves your problem.

Thanks
