Prefix mismatch in node-sass-middleware int nested routes

app.use(
sassMiddleware({
  src: path.join(__dirname, "public", "scss"),
  dest: path.join(__dirname, "public", "css"),
  debug: true,
  outputStyle: "compressed",
  prefix: "/css"
})
);

After first routes load it work fine but in next nested routes main.css gives prifix mismatch error.main.css not loaded to website.

route:- {Localhost:3000/project } | success

[sass]  dest: E:\Web Development\PersonalWeb\public\css\main.css 

route:- {Localhost:3000/project/project-details } | failed

[sass]  skip: /project/project-detail/css/main.css prefix mismatch
