Delete User causes "Unexpected null value" in P12ProfiloWidget after successful account deletion

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When a logged-in user confirms account deletion from the P12-Profilo page, the Firebase Authentication user and the corresponding users document are successfully deleted.

Immediately after the Delete User action completes, the app shows a red error screen with:

“Unexpected null value”

The error-causing widget is reported as:

P12ProfiloWidget

The issue is reproducible every time in Run Mode.

Expected Behavior

After the account is successfully deleted, the user should be signed out and redirected away from P12-Profilo to the app’s unauthenticated entry screen, without any red error screen or runtime exception.

Steps to Reproduce

1. Open the app in Run Mode.
2. Create a new customer account and complete the login flow.
3. Navigate to P12-Profilo.
4. Tap “Elimina account”.
5. Confirm the deletion in the confirmation dialog.
6. The Firebase Authentication user and the corresponding users document are deleted successfully.
7. Immediately after deletion, a red error screen appears with “Unexpected null value” and P12ProfiloWidget is reported as the error-causing widget.

Environment

- FlutterFlow version: v7.0.51
- Platform: Web
- Browser name and version: Google Chrome 149.0.7827.201
- Operating system and version affected: macOS 15.7.7 (24G720)

Additional Information

This issue affects a core account-management flow. The user is deleted successfully from Firebase Authentication and Firestore, but the app immediately crashes with an “Unexpected null value” error instead of returning to a safe unauthenticated page. I am trying to obtain a clean and reliable account deletion flow that completes without showing an error screen.

For cases like this, enable "Navigate Automatically" in the Delete action. Alternatively, after the Delete action, add a Log Out action and configure it to navigate to the initial page.

Hi Alessandro, thank you for the reply.
In my current configuration, “Navigate Automatically” is already enabled in the Delete User action, but the “Unexpected null value” error still occurs immediately after the user is deleted.
I will also test the alternative flow with a Log Out action after Delete User and navigation to the initial page. I’ll report the result here.

I’ve attached a screenshot showing that “Navigate Automatically” is already enabled in the Delete User action.
