PHP 8.2.1 not supported? Can't install because of "unable to parse JSON response" error

[MassiPi]

Hello,
i'm trying to install Winter CMS on a PHP 8.2.1 server with the latest install package (i can't understand the specific version of the install, but it's the 4.748.395 bytes version)
I found information about an old incompatibility with php 8.1, but it got sorted out.
I changed max execution time and max input time directives in my php.ini
Still the same error.
I fear this is coming from the 8.2 version of PHP, because of its "Deprecate dynamic properties RFC".
Indeed, i can see this error server side, that is breaking the JSON and so rising the error while trying to install
Sat Feb 4 09:59:50 2023 daemon.err nginx[8100]: 2023/02/04 09:59:50 [error] 8129#0: *24 FastCGI sent in stderr: "PHP message: PHP Deprecated: Creation of dynamic property Winter\Installer\Api::$log is deprecated in /mnt/sda1/web/cms/install/api/src/Api.php on line 734" while reading response header from upstream, client: 192.168.1.238, server: home.massi.biz, request: "POST /cms/install/api.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php8-fpm.sock:", host: "xxx", referrer: "https://xxx/install.html"
Is there a beta install compatible with php 8.2 to try?
Other ideas to fix?
I thought this could be the issue:
/** @var Logger */ protected $logger; //WRONG name, never used protected $log; //name used in the script, not declared

but even with this i get the error and see no more errors in logread
Thanks

@MassiPi at what point is the installer failing?

[bennothommo]

For what it's worth, I tested with PHP 8.2 with the same setup as you (displaying deprecation errors) and while I saw these errors being thrown, it didn't stop me from completing the installation, albeit I'm running through the CLI server.

[MassiPi]

I'm running through the CLI server.

how can i do that? hopefully to understand where the error is coming from :)

[bennothommo]

I've also released a new version of the Installer with your suggested fix for the $log property. Thanks for that, @MassiPi!

i'm now thinking about that notice about rising memory limit to 1.5Gb.
Obviously my router can't face it, i have a configured limit of 16Mb, can this be the source of the problem?
I tried avoiding the memory increse but i get the same error in the same place..
any idea?
thnks

(sorry i can't understand how to keep newlines in code blocks lol)

[MassiPi]

ok apart from the typo above between logger and log, i'm confident my issue is related with nginx configuration i can't sort out.
I installed (tried to..) the cms in the subfolder /cms but i cant fix the configuration proposed here https://wintercms.com/docs/setup/configuration#nginx-configuration
i fear i'm gonna give up, thanks for the support :)

[LukeTowers]

@bennothommo any ideas here?

[bennothommo]

It could potentially be an issue with PHP 8.2 and Laravel - might be something to do with deprecation notices, but this is just a guess. I can't see anything in the log file that would give us a clue, unfortunately.
