Find and fix errors with Flow Checker
Flow Checker in Power Automate promotes higher quality flows by ensuring you follow best practices when you design flows. When you run the checker, you get insights into questions like "which areas of my flow's implementation pose a performance or reliability risk?"
For each issue the checker identifies, the checker points to specific occurrences within the flow where you should consider making improvements. And, you learn how to implement these improvements by following detailed guidance.
The checker is always active, appearing in the command bar in the designer.
Resolve errors and warnings
While designing your flow, you can select Flow Checker to open the checker to view errors and warnings.
The checker also opens automatically when you save the flow if there are errors or warnings. Once the checker opens, it shows all errors and warnings in your flow. In each section, the checker calls out the actions where the error or warning occurs.
Note
- Power Automate uses either the classic cloud flows designer or the new modern designer with Copilot capabilities. To identify which designer you’re using, go to the Note section in Explore the cloud flows designer.
- When you switch between the classic and new designer, you're asked to save your flow. You can't save and switch until all errors are resolved.
The Flow Checker shows you errors or warnings in your flow. It also provides help to fix the errors and warnings in red on both the action panel and the flow card.
To run the checker, select Flow Checker.
The Flow Checker panel opens.
In the Flow Checker panel, select the error or warning and correct your error with the help of the red text from the checker.
Alternatively, select the red error in the flow card to open the same window where you correct the error.
Run the Flow Checker again. If there are no errors or warnings, you get a message in the Flow Checker panel that says No errors found. We recommend that you test your flow to ensure it works as expected.
