First, we need to enter the meteor interactive shell via the command meteor shell.

Then, follow the below commands to get the message:

➜ meteor shell
> import { Apps } from './app/apps/server/orchestrator'
> manager = Apps.getManager()
> darts=manager.get('Darts-beta')[0]
> dartsZip=darts.getStorageItem('zip').zip
> aff = Promise.await(manager.add(dartsZip))
> aff.getCompilerErrors()

TODO: Need to create a PR for it to make us know the error more easily.
