Read Document action shows 'Unknown' reference and cannot be set (SplashAuthGate & Inloggen pages)

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

On the SplashAuthGate page's On Page Load action flow, and on the Inloggen page's Button On Tap action flow, the 'Backend Call: Read Document' action shows 'Unknown' (highlighted red) for 'Select Reference to Read'. This cannot be resolved through the reference picker. I checked every available option in the picker (Page Parameters, Authenticated User fields, Global Properties, Constants, Action Outputs, Conditional Value, Custom Functions, Random Data, Sample Data) and none offer a usable Doc Reference-typed value.

Expected Behavior

The 'Select Reference to Read' picker should offer a valid Doc Reference option, such as a reference to the current authenticated user's own document in the 'users' collection, so the action can be configured properly and the app can read the user's role to route them correctly after login.

Steps to Reproduce

1. Open the SplashAuthGate page in the Widget Tree.
2. 2. Open the On Page Load action flow.
3. 3. Open Conditional Action 1 (User ID is set) - True branch - Action 1 (Backend Call: Read Document).
4. 4. Observe 'Select Reference to Read' shows 'Unknown' in red.
5. 5. Click the reference picker and note no valid Doc Reference option is available to select.
      Same pattern is reproducible on the Inloggen page: Button - On Tap action flow - Action 2 (Backend Call: Read Document) shows the identical 'Unknown' reference issue.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Visual documentation

(Automated screenshot upload failed in my environment. I have two screenshots ready showing the "Select Reference to Read" field highlighted in red with the "Unknown" value and warning icon - one for SplashAuthGate's On Page Load Action 1, one for Inloggen's Button On Tap Action 2. Happy to attach them manually if needed.)

Environment

- FlutterFlow version: latest available (as of July 2026)
- Platform: Web
- Browser name and version: Chrome
- Operating system and version affected: N/A (issue occurs in the web-based FlutterFlow builder, not platform-specific)

Additional Information

This is blocking a working login/role-routing flow (SplashAuthGate and Inloggen pages), which is needed before we can ship the app to the App Store.
