tRPC CORS error

Hello, I have tRPC setup with express.js and next.js (as the client) within a turborepo and tRPC as a shared package. What am I doing wrong to get a cors error. Any help would be appreciated.

Install the cors express middleware package in your server and add your client to the allowlist.

app.use(cors({ origin: "http://localhost:3000" }))
