I am currently using using [T3 Env](https://env.t3.gg/) for type safe environment variables however on vercel it seems that the server environment variables aren't pulling in for some reason. it builds fine in locally and builds fine using the Vercel CLI using vercel pull and vercel build.

I have checked that my environment variables are correct in my settings and they are and are set for the right environments.
This is the error I see:

$ next build
 ❌ Invalid environment variables: {
   SUPABASE_URI: [ 'Required' ],
   UNSPLASH_SECRET: [ 'Required' ],
   UPLOADTHING_SECRET: [ 'Required' ],
   UPLOADTHING_APP_ID: [ 'Required' ],
   SUPABASE_SERVICE_ROLE: [ 'Required' ],
   GOOGLE_AI_API_KEY: [ 'Required' ],
   UPSTASH_REDIS_REST_URL: [ 'Required' ],
   UPSTASH_REDIS_REST_TOKEN: [ 'Required' ]
 }
