What path to be used for local files which are in public folder in Next js api function

I am using Jimp NPM module for image processing in NextJs api function which is to use a local font situated in public folder, This is working fine in development server but it is giving me errors when deployed to vercel, error says no such file or directory, I even tried using Jimp.FONT_SANS_64_BLACK but still it is giving me the same error.
