            $rules

        $exceptionsTests = [];
        $exceptionsArray = [];
        $children = [];
        $methodChildren = $method->getChildren();

            if (!in_array($validationRules, $existingValidationRules)) {
                foreach ($validationRules as $validationRuleIndex => $validationRule) {

                    // avoid having a validation rule that has already been applied to the attribute within the method which is calling the validate method
                    if (0 === $validationRuleIndex) {
                        $ruleParts = [];

                        if (3 === count($ruleParts) && !empty($ruleParts[1]) && $rules->getRule($ruleParts[1]) instanceof AbstractRule && Rules::hasRuleBeenAppliedToAttribute($rules->getRule($ruleParts[1]), $ruleParts[2], $this->getAttribute())) {

It seems like $rules->getRule($ruleParts[1]) can also be of type null; however, parameter $rule of WsdlToPhp\PackageGenerator\File\Validation\Rules::hasRuleBeenAppliedToAttribute() does only seem to accept WsdlToPhp\PackageGenerator\File\Validation\AbstractRule, maybe add an additional type check?

                        $validationRule = str_replace('throw new', sprintf('%s = new', $exceptionName), $validationRule);
                        $exceptionsTests[] = sprintf('isset(%s)', $exceptionName);
                        $exceptionsArray[] = $exceptionName;
                    }

                }
            }
            $existingValidationRules[] = $validationRules;
