NestJS - Error: The externalDependency 'webpack-cli' for 'project:build' could not be found.

[Fafnur]

Current Behavior

If you add yarn.lock to .gitignore for a monorepo with nestjs, the project will crash with an error.

Error message:

NX   Daemon process terminated and closed the connection

Please rerun the command, which will restart the daemon.
If you get this error again, check for any errors in the daemon process logs found in: /mnt/Storage/Development/angular/nx-gitignore-bug/.nx/workspace-data/d/daemon.log

If you remove yarn.lock from .gitignore, everything is fine.

Expected Behavior

Adding yarn.lock should not affect server startup with yarn.

1. Generate a new workspace with nx
2. Set yarn as default manager in package.json "packageManager": "[email protected]"

I have the same exact problem. Added package-lock.json to gitignore monorepo wouldn't start even after re-cloning the repo and fresh modules install.
Removing package-lock.json from .gitignore instantly fixed it.
