Undeclared Arguments Passed To ViewHelper MaxRange

After updating TYPO3, I get a TYPO3Fluid\Fluid\Core\ViewHelper\Exception "Undeclared arguments passed to ViewHelper ... maxRange Valid arguments are."

use TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface;
use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;

class NumberOfStarsViewHelper extends AbstractViewHelper
{
    /**
     * divides the maxRange with two
     * (A rating of 10 results in 5 Starts e.g.)
     *
     * @param integer $maxRange
     * @return boolean
     */
    public function render($maxRange)
    {
        return array_fill(0, ($maxRange / 2), 'iter');
        //===
    }

}

What can i do? Thanks

Answer

here the solution:

    use TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface;
    use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;
    use TYPO3Fluid\Fluid\Core\ViewHelper\Traits\CompileWithRenderStatic;
    
    
    class NumberOfStarsViewHelper extends AbstractViewHelper
    {
        public function initializeArguments() {
            parent::initializeArguments();
            $this->registerArgument('maxRange', 'string', 'divides the maxRange with two', false, null);
        }
    
        use CompileWithRenderStatic;
    
        public static function renderStatic(
            array $arguments,
            \Closure $renderChildrenClosure,
            RenderingContextInterface $renderingContext
        ) {
            return array_fill(0, ($arguments["maxRange"] / 2), 'iter');
        }
    }
