Classes/Domain/Validator/PasswordValidator.php throws an error when in debug mode but not in live mode

PHP Warning: Trying to access array offset on value of type null in /public/typo3conf/ext/femanager/Classes/Domain/Validator/PasswordValidator.php line 138

 /**
     * Initialize Validator Function
     */
    protected function init()
    {
        $this->configuration = $this->configurationManager->getConfiguration(
            ConfigurationManagerInterface::CONFIGURATION_TYPE_SETTINGS,
            'Femanager',
            'Pi1'
        );
        $this->cObj = $this->configurationManager->getContentObject();
        $this->piVars = GeneralUtility::_GP('tx_femanager_pi1');
        $this->actionName = $this->piVars['__referrer']['@action'];
    }

I called this from my own validator:

public function validatePassword(User $user, string $password): bool {
	  $user->setPassword($password);

	  /** @var PasswordValidator */
	  $validator = GeneralUtility::makeInstance(\In2code\Femanager\Domain\Validator\PasswordValidator::class);
	  $validator->configurationManager = GeneralUtility::makeInstance(ConfigurationManager::class);

	  return $validator->isValid($user);
	}

I think the problem is, that my extension gives another name then this: $this->piVars = GeneralUtility::_GP('tx_femanager_pi1');
in the header:

tx_name_profile[__referrer][@controller]: User
tx_name_profile[__referrer][@action]: showProfile
tx_name_profile[__referrer][@extension]: Name

I checked this and I don't our validators support use cases outside of tx_femanager_ plugins, especially with the switch to v8 and multiple plugins, we now specifically check for things running in one of the allowed plugins through PluginService, so upgrading wouldn't fix this issue either.

Please reimplement the password checking logic in your case here.
