## What happens? 我在拉取[examples](https://github.com/eggjs/examples) demo 代码后，开启sequelize-ts demo代码服务后，请求 /posts/1 接口后发生错误，而开启sequelize代码服务则是正常的 sql: SELECT ``.`id`, ``.`title`, ``.`content`, ``.`user_id`, ``.`created_at`, ``.`updated_at`, ``.`created_at` AS `createdAt`, ``.`updated_at` AS `updatedAt`, ``.`user_id` AS `userId`, `user`.`id` AS `user.id`, `user`.`name`...
