Getting deployment error: ERR_PNPM_OUTDATED_LOCKFILE #188
Description
ERR_PNPM_OUTDATED_LOCKFILE Cannot install with "frozen-lockfile" because pnpm-lock.yaml is not up to date with packages/blog-starter-kit/themes/hashnode/package.json
I have added light/dark theme toggle (based on next-theme) to hashnode theme template & after making changes pushed to github but deployment in vercel is now failing.
Here is the link to the commit: Sandeep-FED@14cbe39#diff-0e32d4cc7fbf6fe7901429366041ecdcc5a3b4b184748d8b53fbc09ccc3a0f53

Hey, I noticed the deployment failure is caused by the pnpm lock.yaml being out of sync with your updated package.json after adding next themes. You can fix it by running pnpm install in packages/blog-starter-kit/themes/hashnode to regenerate the lockfile, then commit and push it. This will resolve the ERR_PNPM_OUTDATED_LOCKFILE issue .
If you want, I can open a PR with the updated lockfile to fix the deployment.
