我要查找role表中的列表
$query = new LeanQuery("_Role");
$post=$query->find();
报错
Catchable fatal error: Argument 1 passed to
LeanCloud\LeanObject::setACL() must be an instance of LeanCloud\LeanACL,
null given, called in
D:\php\WWW\vendor\leancloud\src\LeanCloud\LeanRole.php on line 40
and defined in D:\php\WWW\vendor\leancloud\src\LeanCloud\LeanObject.php on line 202

但是$count = $query->count();
却可以找到数据。怎么解决呢
