Using a recent @upstash/redis in Nuxt, the build fails with RollupError: Could not resolve "./chunk-SMBYCQIJ.js" from "./chunk-SMBYCQIJ.js?commonjs-external" and the client can't initialize. Cause: after the packaging switch from deno to bun+tsup, the export map in the published package was inverted. Pinning to 1.20.0 did not work for everyone, so upgrading was the only reliable path.
