#PowerPlatformTip 15 – ‘try-catch-finally’

💡 Challenge

Flows fail silently without clear error handling, making troubleshooting difficult.

✅ Solution

Implement the try-catch-finally pattern using the official template to handle errors proactively.

🔧 How It’s Done

Here’s how to do it:

1. Add a Try block where you put your main logic.
   🔸 Put core logic inside the Try container.
   🔸 Ensure all critical actions are included.
2. Add a Catch block to handle any errors from the Try block.
   🔸 Configure error handling actions, such as sending notifications.
   🔸 Log error details for troubleshooting.
3. Add a Finally block for cleanup tasks executed after Try or Catch.
   🔸 Perform cleanup actions, like deleting temporary data.
   🔸 Execute common post-processing steps.

🎉 Result

By implementing this pattern, you’ll gain better visibility into flow failures and more control over how your flows behave when things go wrong.

🌟 Key Advantages

🔸 Surface and Handle Failures: No more silent failures; you’ll know exactly what went wrong and where.
🔸 Isolate Cleanup Logic: Keep your flow tidy with a dedicated Finally block for cleanup tasks.
🔸 Improve Reliability: With proper error handling, your flows become more robust and dependable.
