Firebase CloudFirestore PERMISSION_DENIED

Question

I have been using Firebase's Realtime Database for a long time and thinking to try out the new Database because it is scalable and more efficient in querying data but i have this message from my LogCat

PERMISSION_DENIED: Missing or insufficient permissions.

Even though i have user authentication logged in when writing the data i still get this message.

Thanks in advance

Answer 1

The default rules on the Firestore database are: allow read, write: if false; which means you can't read or write to it. Change it to: allow read, write: if request.auth != null;

Answer 2

Set the rules in firestore. I mean, set the read and write rules to anyone, simply change the condition in fire store rules.
