Good evening, I discovered your extension and tried to use it. Saving the content works, but when trying to export I get the above 503 error message from the TYPO3 system.

Info about the TYPO3 system:

• TYPO3 11.5.30
• Operating system: Unix
• PHP version: 8.1.20
• PHP CGI detected: Yes
• Version: MySQL 8.0.33

Please update ext_emconf.php file with following code :

'autoload' => [
        'psr-4' => [
            'Frappant\\FrpFormAnswers\\' => 'Classes',
            'PhpOffice\\PhpSpreadsheet\\' => 'Resources/Private/Vendors/',
            'Psr\\SimpleCache\\' => 'Resources/Private/Vendors/'
        ],
],

Thanks
