我有以下关系表：

我的目标是检索表[resident]中的所有居民。以下是我的代码：

public function getAllResidents(){
    $all_resident = $this->resident_repo->getAll(); //!!error thrown from here!!
}

public function getAll(){
    return $this->findAll();
}

我收到的错误消息是：

我不知道问题出在哪里-我刚开始学习教义。是因为我的[resident]表有[2多对一]关系，也就是[2 inversedby]表[building and doctor]的关系吗？
我已经被困在这里一整天了！一个快速的帮助或者一个我能做的参考会很有帮助。如果需要额外的东西，请告诉我。
