Error 500 during installation on IONOS Shared Webspace when calling up the pre-flight

[puxilein]

Hi,

I'm totally desperate because I just can't get anywhere. I followed the instructions at https://snipe-it.readme.io/docs/installation step by step. But as soon as I try to access the website, I get an Error 500. Unfortunately, there is nothing useful in the logs.

What I'm using: PHP 8.4, MySQL
The web space is connected to the “public” directory.

When I enter “https://domain.tld,” I am redirected to “https://domain.tld/login.”

I also set the logs to debug in .env, but unfortunately the storage/logs/laravel.log file remains empty.
The only thing that differs in my installation process is that during installation, when running “php8.4-cli artisan key:generate,” I received the following error message:

 artisan key:generate Error Class "Laravel\Telescope\TelescopeServiceProvider" not found at vendor/laravel/framework/src/Illuminate/Foundation/Application.php:961 957
▕ * @return \Illuminate\Support\ServiceProvider 958
▕ */ 959▕ public function resolveProvider($provider) 960
▕ { ➜ 961▕ return new $provider($this); 962
▕ } 963
▕ 964
▕ /** 965
▕ * Mark the given provider as registered. +1 vendor frames 2 app/Providers/AppServiceProvider.php:90 Illuminate\Foundation\Application::register() +7 vendor frames 10 artisan:33 Illuminate\Foundation\Console\Kernel::handle()

I then commented out the following lines in the app/Providers/AppServiceProvider.php file and was able to continue with the setup:

       if ($this->app->environment('local')) {
            #$this->app->register(\Laravel\Telescope\TelescopeServiceProvider::class);
            #$this->app->register(TelescopeServiceProvider::class);
        }

The following PHP modules are installed:

php8.4-cli -m

The only difference between cli and web is that the web installation still includes the cgi-fcgi module. The rest appears to be identical.

If you need more information (about the available PHP modules or anything else), please let me know and I will provide it.

The web server is a Debian 11.11 installation.

I am grateful for any idea that helps me get the software up and running.

Thank you very much,

Peter
PS: I can select different PHP versions at IONOS and have already tried version 8.1, for example. But I have the same problem there :-(

After trying again and again...

Solution: in .htaccess (in folder "public") was this entry missed:
RewriteBase /
After adding, it worked well!
hth.
