How to Fix Power Apps Form Processor Checkboxes Returning No Data

Product: Power Apps / AI Builder
Device & OS: not provided
Scenario: Extracting checkbox and text data from documents using the AI Builder form processor control within a Power Apps canvas app.
Observed behavior: Checkbox results return no data or null values due to an apparent model connection timeout or bug, even though the rest of the form fields process correctly.

Before you start

Ensure you have the necessary environment permissions to edit the canvas app in Power Apps Studio and that your AI Builder model is successfully published.

Solution 1Recommended

Refresh the AI Builder Model Connection

Switching the connected AI model back and forth forces Power Apps to refresh the connection, which resolves temporary timeout bugs affecting checkboxes.

This issue is often caused by a background bug or timeout related to the AI model connection within the canvas app. Manually toggling the selected model forces the app to re-establish the connection and properly pull all field data, including boolean checkbox values.

Open your canvas app in Edit Mode

Navigate to Power Apps Studio, select the affected application, and open it in Edit mode.

Select the Form Processor control

Click on the specific AI Builder Form Processor control on your screen that is failing to return checkbox data.

Change to a different AI model

In the right-hand properties pane, locate the AI model dropdown and temporarily switch it to any other available model.

Switch back to the original model

Once the control updates, click the dropdown again and reselect your original document processing model.

Test the application

Run the app in preview mode, upload a test document, and verify that the checkbox results are now returning properly.

Connection Restored: This simple toggle clears the timeout bug. If the issue happens frequently, keep an eye on Microsoft Power Platform service health updates.

Solution 2

Create a New Form Processor Control

If refreshing the model connection fails, replacing the control entirely ensures a clean integration with the AI Builder service.

Frequently Asked Questions

Why do only checkbox fields stop returning data in AI Builder?

Checkbox fields extract boolean values, which can be more susceptible to connection timeouts or minor background sync errors in Power Apps. While text extraction might continue to function from cache or partial syncs, checkbox states may return null if the model connection isn't perfectly maintained.

Do I need to retrain my AI Builder model to fix this issue?

No, retraining is usually unnecessary if the model previously worked well. The issue is typically related to how the Power Apps canvas control connects to the model. Toggling the connection in the app is often enough to resolve it.

How can I check if AI Builder is experiencing a service outage?

You can verify the service health of AI Builder by visiting the Microsoft Power Platform admin center, navigating to the Help + Support section, or by viewing the Microsoft 365 admin center Service health dashboard for any reported incidents.
