Issue
I see this issue when I try to use the FlutterFlow Content Manager (CMS)
Error updating Firestore Security Rules... Make sure you set up Firebase for your project under "Settings" > "Firebase".
Why You Are Seeing This Error
You are seeing this error because your Firebase permission have not been set up correctly. No worries, this is easy to fix!
Ensure Email Sign-In Is Enabled
Open the Firebase console, and click on Authentication (in the left side menu).
Click on the Get started button.
Select the Sign-in method tab.
Check to see if you see Email/Password with that is turned on with a green check Enabled:
If you don't see this, you will need to use these instructions to turn on email sign-in.
Ensure you have added the required cloud permissions
For push notifications to work, you will need to add the following cloud permissions for firebase@flutterflow.io: Editor, Cloud Functions Admin, and Service Account.
Head to the Firebase Console and open the project dashboard for your project (click the project tile). Select Project Settings > Users & Permissions.
If you don't have Cloud Functions Admin, Editor, and Service Account listed next to firebase@flutterflow.io, you have not completed this step.
Here are the instructions on how to add the required cloud permissions to your project.
Update Your Firebase Rules
From within your FlutterFlow project, select Firestore > Settings > Scroll down to Firestore Rules > select Deploy/Redploy.
Ensure Firebase Schema Is Defined
Ensure you have defined the fields in your Firebase schema. Only fields defined in your Firebase schema are shown in the Firebase Content Manager.
Ensure you are using the latest version of FlutterFlow
To upgrade to the latest version of FlutterFlow select Ctrl + R on Windows or Cmd + R on Mac.
After you have done this, clear your browser cache and log out/in to FlutterFlow.

Create Permissions From Scratch
If you have already completed the above steps, the final troubleshooting method is to remove the existing permissions and complete a new setup from scratch. Here are instructions on how to do this.
