 1. `npm ci` fails with a typescript compilation error about a missing package.

+2. The software builds locally but fails in CI, or vice-versa.
    This error likely means that some local build caches need to be cleaned.
    The build error may not indicate that this is a caching issue, e.g., it may appear that the packages are being built in the wrong order.
    Delete `node_modules/`, `lib/` and `tsconfig.tsbuildinfo` from each package's subdirectory. then try again.
+3. `npm ci` fails due to wrong node version. Make sure to be using `v18`. Node version `v21` is not supported and known to cause issues.
