Description
I just abstracted @vercel/kv into a Turborepo package to use a shared client between my apps using createClient. My local builds are fine but on Vercel my build fails with the error in the title. Here's my client creation code:
import { createClient } from "@vercel/kv";
export const kv = createClient({
url: process.env.KV_REST_API_URL,
token: process.env.KV_REST_API_TOKEN,
});
My environment variables are stored in the root .env file.

Research direction
Start with the shared Turborepo package, the root .env file, and the createClient call shown in the issue. Trace how environment variables reach that package during a Vercel build and reproduce the missing-url failure; done means the build receives the required Redis configuration without breaking local builds.
