fluid:schema:generate - throw an exception

[ryze-typo3-developer]

In TYPO3 v13.3 if i am on the console run "vendor/bin/typo3 fluid:schema:generate" it throw an exception:

Uncaught TYPO3 Exception Typed property Brotkrueml\Schema\Core\ViewHelpers\AbstractTypeViewHelper::$modelTemplate must not be accessed before initialization thrown in file /var/www/html/domains/ryze-typo3-standard/vendor/brotkrueml/schema/Classes/Core/ViewHelpers/AbstractTypeViewHelper.php in line 41

@ryze-typo3-developer Thanks for your report. Sadly, this cannot be fixed easily on my side. If I adjust the $modelTemplate part another error occurs:

Uncaught TYPO3 Exception Call to a member function getPropertyNames() on null

It seems that the command also collects abstract view helper classes (which it shouldn't) - will have a look into the command.

Okay, it is not the AbstractTypeViewHelper, but the first type view helper found: schema/Classes/ViewHelpers/Type/BeachViewHelper.php

It is this part of code in \TYPO3Fluid\Fluid\Schema\ViewHelperMetadataFactory who produces the error:

(new \ReflectionClass($className))->newInstanceWithoutConstructor()->prepareArguments()

Will take care, but have to think about this.

First step: don't abort generating the XSDs:
