Identify the Error via Flow History

1. Select Solution where the flow is deployed/available.

2. Select the failed flow or select the link in the flow failure notification mail sent from the sample flow to directly go to the flow.

3. In the 28-day run history section, select the date of the flow run that failed. Microsoft Power Automate displays the details of the flow with at least one step with a red exclamation icon.

   

4. Open the failed step and review the error message. Microsoft Power Automate displays details of the error and the solution to fix the error in the right pane.
