Why does my build fail after updating packages?
Usually because a package jumped a major version, which can change how it works, or because package.json and the no longer match, so the build server installs different versions than your laptop or refuses to install. Update one package at a time, read upgrade notes for major versions, and commit the lockfile with package.json.
Breaks at Hosting: Lockfile out of sync with package.json
