This should be resolved in v11.1.0 (which is going out today). Sorry for not getting the fix out sooner.

Workaround I used to get around this. Grab the Realtime DB rules from your console, and create a database.rules.json file manually locally. Remove the comments (as mentioned above) and ensure you have a well formed json and EOF.

Then run firebase init, and say N when prompted if you should overwrite the existing database.storage.rules. Rest of the init completes.
