这是我第一次将rails应用程序部署到生产环境中。我想部署到Fly。IO和已创建的凭据和启动的文件飞行。部署的IO配置文件。但是当我部署时，我得到以下错误:

我遵循了来自GoRails的Chris Oliver给出的指示;Deanin，但这没有任何帮助，因为他们可以把它弄起来;只运行几个命令。我相信我的问题在我的配置/数据库/yml文件中，但我能够找出具体细节。
关于我应该如何调试这个问题有什么想法吗?
我注意到这个问题，因为迁移到v2。我通过在飞行中检查一个项目来解决这个问题。toml文件:
- App名称正确(第6行)
一旦我纠正了这个，我遇到了另一个问题。在同一文档中，端口号似乎也需要更新。
