I need to store files in ./output/public and get them after storing. Also i have to mount my file-storage by setting absolute path of public dir (in prod it is /output/public). On other hosting platforms my path 'path.join(process.cwd(), '.output/public')' works fine, but on vercel i always get the issue of unknown dir, mkdir /vercel. I tried to use __dirname instead of process.cwd and etc. All these ways dont work with vercel. Someone, help me
