Hi,

When you actually use firebase init command, do you use an existing project? In this case, you should check your Realtime Database rules directly in your firebase console, because Firebase Init will try to copy it in local. Try to delete all comments in.

My realtime database rules looks like this:

Which matches the content of the request body posted in my original message

"{\n /* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */\n \"rules\": {\n \".read\": false,\n \".write\": false\n }\n}"

But it seems escaping characters with \ isn't working properly after the response.

Try to add an EOF in your json rules. (7th empty line)

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.

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