Translate cryptic Power Automate cloud flow error codes into plain English and get actionable fixes — right inside the designer.
Free Chrome Extension
Error Explainer
Install the Error Explainer extension
Search for Power Automate Error Explainer on the Chrome Web Store and click Add to Chrome. Once installed, the extension activates automatically whenever you have a Power Automate cloud flow open in the designer.
Trigger or find an error in your flow
Run your flow or open a recent run that failed. In the run history, click on the failed run to expand it. Locate the action that shows a red error badge. Click on the action to see the raw error message and error code that Power Automate provides.
Open the Error Explainer panel
Click the Error Explainer icon in your Chrome toolbar to open the side panel. The panel is aware of the current page context so it can detect error messages visible in the designer automatically, or you can paste the error manually.
Read the plain-English explanation
Error Explainer translates the error into a clear, human-readable explanation. It identifies whether the error originated in the designer (configuration issue), at runtime (logic or data issue), from a connection (authentication or permissions), or from a connector (service-side problem). This immediately narrows down where to look.
Follow the suggested fix
Below the explanation, the tool provides a step-by-step fix tailored to the specific error type. For connection errors it tells you which connection to re-authenticate. For runtime errors it suggests which action inputs to review. For configuration errors it highlights the field most likely causing the problem.
Apply the fix and re-test
Make the suggested change in the flow designer — re-enter a connection, adjust an expression, fix an action input — then save the flow and trigger a new run. Use the run history to confirm the previously failing action now succeeds.
All done!
You are ready to use Error Explainer like a pro.
