zapier push failing with 'Looks like you're missing a local installation of zapier-platform-core' in an npm workspaces monorepo: the CLI does not resolve workspace-installed packages. Reporter's workaround: temporarily remove the workspace entry from the root package.json, then from the adapter directory run npm install, npm run build, and npx zapier push.
