在 app.yml 文件中错误地添加了一个无效的 GitHub 存储库后，我的 Discourse 站点出现了一个问题。当我运行 ./launcher rebuild app 时，进程失败，现在站点无法重建。不幸的是，我有备份，但它们在恢复过程中失败。以下是问题的详细信息，包括完整的错误日志。
已采取的步骤：
- 我尝试按照此帖子中的指导，将 DeepSeek LLM 添加到我的 Discourse 安装中。
- 我将存储库 URL
https://github.com/deepseek-ai/DeepSeek-LLM添加到了app.yml文件中。 - 运行
./launcher rebuild app，但失败了，导致站点无法运行。

挑战：
- 我无法从备份中恢复站点。
- 重建持续失败，导致站点无法运行。
求助：
- 我该如何处理这些问题？运行 rebuild app 是否创建了一个有问题的插件或类似的东西？
- 是否有任何手动恢复步骤？
- 关于如何安全地从这种状态重建站点的任何建议？
我注册了一个托管的 Discourse 实例，并上传了备份，但即使文件正常上传，恢复选项也没有出现。
我非常感谢关于如何继续的任何建议或指导。如果需要更多详细信息，请告诉我！
