"KV_REST_API_URL" is not exported by "virtual:$env/static/private" - When deploying to Vercel

[salaheddine66]

error during build:

19:56:30.642 | RollupError: src/routes/api/getRecommendation/+server.ts (2:25): "KV_REST_API_URL" is not exported by "virtual:$env/static/private", imported by "src/routes/api/getRecommendation/+server.ts".
