npm warn deprecated @vercel/kv@3.0.0: Vercel KV is deprecated. If you had an existing KV store, it should have moved to Upstash Redis which you will see under Vercel Integrations.

npm prints the package's deprecation notice on install. The Vercel KV product was sunset, and existing stores were moved to Upstash Redis.

Why it happens

@vercel/kv 3.0.0 is the last release. The registry message points new projects to a Redis integration from the Vercel Marketplace.

Manual fix

npm uninstall @vercel/kv && npm install @upstash/redis

// before
import { kv } from '@vercel/kv'
// after
import { Redis } from '@upstash/redis'
const kv = Redis.fromEnv()   // reads UPSTASH_REDIS_REST_URL / UPSTASH_REDIS_REST_TOKEN

Verify

Re-run your install/build and re-scan the file above. The finding should be gone. The paid fixer applies the same change across a repo: --dry-run shows the diff, --apply keeps a .bak of each file, and --rollback restores them.
