When I run the rector script bin/cake upgrade rector --rules cakephp40 ../project/src I get the following error:
Notice: Undefined property: PhpParser\Node\Stmt\ClassMethod::$attrGroups in phar:///Users/uscreen/Sites/upgrade/vendor/phpstan/phpstan/phpstan.phar/vendor/nikic/php-parser/lib/PhpParser/NodeVisitor/NameResolver.php on line 216

Fatal error: PHPStan\Analyser\MutatingScope cannot implement PHPStan\Analyser\Scope - it is not an interface in phar:///Users/uscreen/Sites/upgrade/vendor/phpstan/phpstan/phpstan.phar/src/Analyser/MutatingScope.php on line 92
The script then exits with no changes made, but it echos Rector applied successfully. I don`t know where to start to debug this.
