我尝试部署一个简单的Flask应用程序，使用SQLite数据库，在本地运行时运行良好，我通过Github将其部署在Vercel上，直到需要写入数据库时才停止工作，然后是

OperationalError: attempt to write a readonly database

DB和包含它的文件夹“instance”在我的本地系统上都是完全访问权限，我可以用

attrib ~/instance

在命令行中（我使用的是Windows 10）。有没有办法直接在Github repo上检查和更改文件或文件夹的访问模式？
以下是有关此错误的日志：

我在本地系统中以User和Admin身份仔细检查了DB的访问模式
