Debugging in Power Apps

Question

I'm developing a Canvas App in Power Apps, but I'm facing issues where some functions aren't working as expected, and errors occasionally appear. I want to identify and fix these issues efficiently.

What are the best ways to debug and handle errors in Power Apps?

The best ways to debug and handle errors in Power Apps

To debug and handle errors in Power Apps efficiently, follow these best practices:

1. Use the "Monitor" Tool

1. In Power Apps Studio, go to Advanced tools > Live Monitor.
2. This tool tracks app performance, errors, and API calls in real time.
3. Identify issues by running the app and reviewing logs for failed operations.

2. Implement Error Handling with IfError and IsError

Wrap risky operations with IfError() to catch errors and take alternative actions.

IfError(
   Patch(Orders, Defaults(Orders), {Title: OrderTitle.Text}),
   Notify("Failed to submit order. Please try again.", NotificationType.Error)
)

If the operation fails, it shows a notification instead of breaking the app.

3. Enable "Formula-Level Error Management"

Go to File > Settings > Upcoming Features > Experimental and enable Formula-level error management.

This helps detect formula issues and provides clearer debugging insights. Read ,more at Error handling

4. Debug API Calls and Data Connections

Use Notify() to display error messages when a Power Automate flow or data source fails.

If(
    IsEmpty(OrdersCollection),
    Notify("No orders found. Please check your connection.", NotificationType.Warning)
)

5. Review App Checker for Issues

• Click on File > App Checker to detect formula errors, accessibility issues, and missing references.
• Fix any red warnings to improve app stability.
