react-native-firebase realtime database .ref doesn't work

Question

I can't read or write into my database, so I was trying to figure out the problem.

When I run console.log(database().ref("/users/123")); I get "null/users/123"

But when I try this with firestore console.log(firestore().doc("users/" + userId)); I get a long message {"_documentPath": {"_parts": ["users", "Gz7eG1y7qWX6Q9gijSPDlcLcZop1"]}, ...

When I run console.log(database()); I get a long message {"_app": {"_automaticDataCollectionEnabled": true, "_deleteApp": [Function bound deleteApp], ...

From this I assume that my firebase setup is correct, there should be a problem with the ref function.

Could you guys help?

I use "@react-native-firebase/app": "^12.0.0", "@react-native-firebase/database": "^12.0.0", "@react-native-firebase/firestore": "^12.0.0", "react-native": "0.63.4",
